OK HOW TO SLOVE INTERIOR ANGLES?

x= 32

∠ABC= 79

∠ACB= 64

Step-by-step explanation:

To solve interior angles, remember that a triangle always sums up to 180 degrees. So, all the angles added together should equal to 180 degrees.

The equation would be: 2x+15+2x+37= 180

Step 1- Add common variables.

(2x+2x)+(15+37)= 180

4x+52= 180

Step 2- Subtract 52 to both sides.

4x+52= 180

   -52    -52

4x= 128

Step 3- Divide both sides by 4.

4x= 128

4     4

x= 32

Now that we know the value of x, substitute it into the angles.

∠ABC= 2(32)+15= 79

∠ACB= 2(32)= 64

Check          

Add all the angles together to make sure they sum up to 180 degrees.

79+64+37= 180

Hope this helps!

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
