Answer:

Step-by-step explanation:

Pythagorean theorem: base ² +altitude² = hypotenuse²

1) hypotenuse² = base² + altitude²

          x² = 6² + 3²

               = 36 + 9

               = 45

         x = √45

         x = 6.7 cm

4) base ² +altitude² = hypotenuse²

x ² + 3.7 ² =  4.2 ²

x ² + 13.69 = 17.64

             x ² = 17.64 - 13.69 = 3.95

             x = √3.95

            x = 1.99 cm

10)c ² = a ² + b ²

           = 3 ² +4 ²

         = 9 + 16

  c ² = 25

c = √25 = 5

11) a ² + b ² = c ²

9 ² +b² = 13 ²

81 + b² = 169

     b² = 169 - 81 = 88

b = 9.38

12) a² + b² = c²

12² + b² = 22²

  144 + b² = 484

           b² = 484 - 144 = 340

           b =√340 = 18.44

Answers

Answer:

33 miles

Step-by-step explanation:

The cyclist traveled for 3 hours ar 11 miles per house to find how many miles she traveled simply multiply the speed times the amount of time traveled 11 times 3 is 33

1 hour = 11 miles

3 hours = 11 x 3 miles

             = 33 miles.

Ans: 33 miles

We know x = 4 + y  (1)

Answer:

Y-intercept is at 1 and slope of the graph is 2

Step-by-step explanation:

When plotting this equation use the formula y=mx+b. The variable B is the y intercept its where you start your graph. The variable M is the slope and for that you use rise/run.

To graph 2 you would start at 1 because it's the int. And u would go up 2 and right 1 and just follow that pattern

what is the slope of the line

Answers

Answer:

1.5 OR 3/2

Step-by-step explanation:

Slope (m) = ΔY/ΔX= 3/2=1.5

θ = arctan(ΔY/Δx)= 56.30993247402°

ΔX = 3 – 1 = 2

ΔY = 0 – -3 = 3

Distance (d) = √ΔX2 + ΔY2 = √13 = 3.605551275464

Equation of the line:

y = 1.5x – 4.5

or

y=3/2x-9/2

Thus, 3/2

Answer:

m = 1.5

Step-by-step explanation:

Use the coordinates of two points on the graph:

(1, -3), (3, 0)

Find the slope using slope formula:

m = (y₂ - y₁)/(x₂ - x₁)m = (0 - (-3))/(3 - 1) = 3/2 = 1.5

Which answer is correct? Explain below.

Serin's Answer: The measure of Angle G is 70 degrees. Since the base angles are congruent, the measure of Angel F is also 70degrees.This leaves 40 degrees for Angle E.

Lam's Answer: The measure of angle G is 70degrees. Since an isosceles triangle has two congruent angles, the measure of Angle E and Angle F must be 55degrees

O Both are correct.

ONeither is correct.

Answers

Answer:

∆EFG has an exterior angle at G which has a measure of 110°. Which answer is incorrect ... Since external angle is 110 degrees, the internal is 70 degrees

Step-by-step explanation:

no problem we all get stuck

The angles can be ∠ G  = 70°, ∠ F = 70° and ∠E =  40° or ∠ G  = 70°, ∠ F = ∠ E = 55° hence both are correct so, option C is correct.

What is triangle?

Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Given:

The triangle is isosceles, and AEFG has an exterior angle at which has a measure of 110°,

Calculate the interior angles of the triangle as shown below,

∠ G = 180 - 110  (exterior angle)

∠ G  = 70°

Since the remaining angles can be ∠ F = 70° and ∠E = 180 - 70 + 70 = 40°

or ∠ F = ∠ E = 55°

What is Percentage?

Percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part.

Given that

There are 254 counties in the state of Texas. Pedro says that there are about 250 counties in the state.

There are actually 254 counties.

The amount of error in Pedro's estimate is 4.

Now we need to find percent error in Pedro's estimate.

4/254×100

The perimeter of an equilateral triangle is 24 cm. Find the length of each sides

Answers

Answer:

8cm

Step-by-step explanation:

An equilateral triangle means that all the sides are equal (the same length). A triangle has 3 sides so all we have to do is:

24/3 = 8

Each side is 8cm long

Answer:

Length of each sides = 8 cm

Step-by-step explanation:

Given the perimeter of an equilateral triangle, 24 cm:

Equilateral triangles have three congruent sides.

Hence, to find the length of an equilateral triangle, simply divide the perimeter by 3 (since an equilateral triangle has three equal sides).

Perimeter of an equilateral triangle = 24 cm

Side = 24 cm ÷ 3 = 8 cm

Therefore, the length of each side is 8 cm.
