Answer:

Answers are highlighted with ((x)) ANSWERS FOR WHOLE PAGE ARE:

Step-by-step explanation:

x2+ ((-8))

x=((9))

Add ((16)) to each side x^2-8x=9

Now that you have x2-8x=16=9=16, apply the square root property of addition ((A))

Choose the solutions to the quadratic equation x^2-8x-9=0

((-1, 9))

M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30

n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found

t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98

use the earlier reasoning to fine the other answers of

p=71°
q=39°

use the angle degrees formula to get Pentagon's maximum angles then use earlier resources

the final answers u should be able to figure out from there and u will never learn unless you do some yourself

Solve for C.<br> -5/8c=20
iris [78.8K]
-5/8c = 20....multiply both sides by -8/5 (this cancels out the -5/8 on the left
c = 20(-8/5)
c = -160/5
c = - 32

check..
-5/8(-32) = 20
160/8 = 20
20 = 20 (correct)

so c = -32
