An angle r and it's complement are in the ratio 2: 7.what is measure in degrees of angle r?

Step-by-step explanation:

Two angles are said to be complementary if they sum up to be .

Their ratio is given to be 2: 7 , that is

2x + 7x = 90

9x = 90

x = 10 Therefore : the measure of R is 2x , which is 2 x 10 =

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
