Pls help me number 8 plsssss

Answer:

In a 45°−45°−90° triangle, the length of the hypotenuse is √2 times the length of a leg. To see why this is so, note that by the Converse of the Pythagorean Theorem , these values make the triangle a right triangle. Note that an isosceles right triangle must be a 45°−45°−90° triangle.

Answer:

x = 4

Step-by-step explanation

2x−5+x=−x+7+x

3x−5=7

3x−5+5=7+5

3x=12

x=4

Answer:

x = 4

Step-by-step explanation:

You need to isolate the variable on one side first so that the equation is easier to solve.  To do that, add x to both sides to get 2x + x, which is 3x.  This gets rid of the -x on the other side and results with the new equation

3x - 5 = 7.   Add 5 to both sides to get 3x = 12, then divide both sides by 3 to get x = 4.  

You can check your work by plugging in 4 for x.  

2(4) - 5 = -(4) + 7

8 - 5 = 3

3 = 3

Therefore, x is equal to 4.  

Hope this helped!  Have a good day!  

Answer:

i think it is 50ft but i'm not too sure

Step-by-step explanation:

if you take the 100ft and than use the 20 degrees and divide them you get 50 ? so maybe, just 100 divided by 20

Answer:

18

Step-by-step explanation:

properties of a triangle: all the angles add up to 180 degrees

so

180 - 90 - 72 = 18

answer is 18 degrees

Answer:

653.91 squared or 326.955 not squared

Step-by-step explanation:

We have a hyponuse of 26 and one leg of 4.7 and we are trying to figure out the missing leg!

The first step is

A^2 + B^2 = C^2

2 step

4.7^2 + B^2 = 26^2

3 step

4.7 x 4.7 =  22.09  and 26 x 26 = 676

4 step

22.09 + B^2 = 676

5 step

676 - 22.09 = 653.91

6 step

Answer

653.91 squared or 326.955 not squared!

Answer:

B

Step-by-step explanation:

A right triangle is formed by the ground, the side of the house and the ladder.

The hypotenuse is the ladder

let the side of the house be h

Using the sine ratio in the right triangle formed, then

sin77° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{22}[/tex] ( multiply both sides by 22 )

22 × sin77° = h , then

h ≈ 21.44 ( to the nearest hundredth )

The ladder reaches 21.44 ft up the side of the house

Answer:

504 cm squared

Step-by-step explanation:

14 * 14 = 196

14 / 2 = 7

7 * 11 = 77

77 * 4 = 308

308 + 196 = 504

504

Answer:

400/2.5 = 720/x

400x = 720 x 2.5

x = 4.5

Step-by-step explanation:

The required hours it would take to paint the entire platform is given as x/720. Where x is the length of measure of the platform.

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
Maya’s crew paints the platform at a rate of 720 feet per hour,
Let the length of the platform be x,
Now,
Divide  the length with the rate, giving the time to paint the complete platform,
Time = length/rate
Time = x / 720

Thus, the required hours it would take to paint the entire platform is given as x / 720. Where x is the length of measure of the platform.

Area = base x height

A = 6 in x 5 in

A = 30 in²

Answer:

C. x = 3.71

Step-by-step explanation:

4 + 9(ln x) = 15.8

Subtract 4 from both sides.

9(ln x) = 11.8

Divide both sides by 9.

ln x = 11.8/9

x = e^(11.8/9)

x = 3.71

4 + 9 • In x = 15.8

x= 3.71
