A pair of parallel lines is cut by a transversal: A pair of parallel lines is cut by a transversal. The interior angle made on the left by the intersection of the upper parallel line and the transversal is divided into 2 parts by a slanting line. One part of this angle is labeled as x, and the other part is labeled as 30 degrees. The interior angle made on the right by the intersection of the lower parallel line and the transversal is labeled as 75 degrees. What is the measure of angle x? (1 point)

Answers

Answer:

Step-by-step explanation:

Use the diagram in the attachment for reference. You can substitute the values given in question in place of the one in the diagram.

From the diagram, it can be seen that the sum of angle x and 20 is equal to angle 75 degrees i.e x+30 = 75 (alternate angles)

Next is to find the value of x from the equation

x+30 = 75

Subtract 30 from both sides of the equation;  

x+30-30 = 75-30

x = 75-30

x = 45

Hence the measure of angle x is 45°

Answer:

The answer is 45

Answers

Let me know if you want the answer, but what you need to do first is get the opposite angles.

They're on straight lines, so 180 minus that angle would equal the angle inside the triangle.

Then all inner angles if a triangle add up to 180° so 180 minus the two other angle would give you the final missing angle.

Do the straight line thing again and subtract 156 from it.

Answers

Answer:

7 1/2

Step-by-step explanation:

Let's add the whole numbers first, 3 + 4 = 7

Then, we add the fraction, and since the denominator is the same, there's no need for a change, so we just add the top. 1/8 + 3/8 is 4/8, which can be simplified to 1/2

so answer is 7 1/2

A parking lot has 88 parking spaces. Of those, 4 are reserved for disability parking, 48 are for full-size cars, and the remaining spaces are for compact cars. What is the ratio of compact spaces to full-size spaces?

Answers

The total parking space is 88. 4 are reserved which leaves us with 84. 48 of the remaining cars are for full size cars with a remaining of 36 cars that are compact cars. The ratio of compact to full size is 36:48 to simplify it divide by 3 on bot sides. You get a ratio of 3:4

What is the equation of the line that is parallel to the
given line and passes through the point (-2, 2)?
O y=1/5x+4
Oy= 1/5x+12/5
O y = -5x + 4
O y=-5x +12/5

Answers

The equation of the parallel line that passes through the point (-2, 2) is y= (1/5) x + (12/5)

What is meant by line's slope?The slope of a line indicates how steep it is. Slope is defined mathematically as "rise over run." Choose two points on the line and calculate their coordinates. Determine the difference in y-coordinates between these two points. Determine the difference in x-coordinates between these two points. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).There are four types of slopes: negative, positive, zero, and undefined. as x grows The slope of a line can also be interpreted as the "average rate of change."

Therefore,

The slopes of the two lines will be the same because it runs parallel to the line predicted by the equation.

The slope of the line is 1/5,

We know that the line is y= (1/5) x + c.

We can now find the y-intercept using the given point (-2,2).

[tex]$&\Rightarrow y=m x+c \\[/tex]

[tex]&y^2=\frac{1}{5}(-2)+c \\[/tex]

[tex]&\Rightarrow^2=\frac{-2}{5}+c \\[/tex]

[tex]&\Rightarrow c=2+\frac{2}{5}=\frac{10+2}{5}=\frac{12}{5} \\[/tex]

[tex]&\Rightarrow c=\frac{12}{5}[/tex]

Hence, The line's final equation will be [tex]y=\frac{1}{5} x+\frac{12}{5}[/tex]

phone carriers.


Find the probability that the selected subject is not male.

Answers

Answer: 0.23

Step-by-step explanation:

Given that:

Percentage population of males = 77% = 0.77

Hence,

Percentage that aren't male = ( 1 - 0.77) = 0.23

P(males) = 0.77

Hence,

P(non-males) = 1 - 0.77 = 0.23

BOXES Simon will make a box without a top by cutting out corners of equal size from a 22 inch by 15 inch sheet of cardboard and folding up the sides. Which of the following is closest to the greatest possible volume of the box?

a. 330 in3
b. 144 in3
c. 432 in3
d. 1296 in3

Answers

Answer:

Volume of box is [tex]432 in^3[/tex]

Step-by-step explanation:

Let x be the side of square corner

Length of box after cutting corners =22-2x

Breadth of box after cutting corners =15-2x

Height =x

Volume of box = (22-2x)(15-2x)x

Volume of box =[tex]4x^3-74x^2+330x[/tex]

Differentiate w.r.t x

[tex]\frac{dV}{dx}=12x^2-148x+330[/tex]

Substitute derivative =0

[tex]12x^2-148x+330=0\\x=\frac{37-\sqrt{379}}{6},\frac{37+\sqrt{379}}{6}\\\frac{d^2V}{dx^2}=24x-148[/tex]

at [tex]x=\frac{37-\sqrt{379}}{6}[/tex]

[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37-\sqrt{379}}{6} )-148=-77.87 < 0[/tex] hence maximum

at  [tex]x=\frac{37+\sqrt{379}}{6}[/tex]

[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37+\sqrt{379}}{6} )-148=77.87>0[/tex] hence minimum

So,Volume of box =[tex]4x^3-74x^2+330x=4(\frac{37-\sqrt{379}}{6} )^3-74(\frac{37-\sqrt{379}}{6} )^2+330(\frac{37-\sqrt{379}}{6} )=432.23 in^3[/tex]

Hence Volume of box is [tex]432 in^3[/tex]
