Lines L And M Are Parallel, Find M&lt;7

Answers

Answer 1

Answer:

142°

Step-by-step explanation:

Lines L and M are parallel and a line is transversal to them.

[tex]\therefore 38 \degree + m \angle7 = 180 \degree \\ (straight \: line \: \angle s) \\ \\ \therefore m \angle7 = 180 \degree - 38 \degree \\ \\ \huge \red { \boxed{\therefore m \angle7 = 142 \degree }}[/tex]

I have no idea where to start

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.

3 1/8 +4 3/8 solve the question

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

If 6x + 4 = 11x - 21, what is the value of x?

Answers

Answer:

x = 5

Step-by-step explanation:

11x - 6x = 4 + 21

5x = 25 (÷5)

x = 5

X=5

Explanation: 6x + 4 = 11x - 21
1). Subtract 4 from both sides and you will get 6x = 11x -25.
2). Subtract 11x from both sides and you should get -5x = -25.
3). Divide the -5 with -25 to get x alone and you should get X=5!

Check your work:
6(5) + 4 = 34 & 11(5) - 21 = 34
34=34.

Answers

You can break the 200 into sqrt 100*2. We can see the 100 has a perfect root, that’s 10. But the 2 does not. So take the 10 out and multiply it by the sqrt 2

In Akutan, Alaska, men are 77% of the population. It is also known 11.3% of

Akutan males smoke cigars while 2.1% of Akutan females smoke cigars. One

member of the population is selected at random for a survey involving cell

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

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°

The answer is 45
