Question

Can you anser number 9

Answer 1

`x = (367)/(3)`

`y = (173)/(3)`

Explanation:

Equations

Let's call

x = measure of angle 1

y = measure of angle 2

The angles are supplementary, thus their sum is 180°:

x + y = 180 [1]

It's also known that one angle (x) is 7° more than twice the other (y), thus:

x = 7+ 2y [2]

Substituting [2} in [1]:

7+ 2y + y = 180

Operating:

7+ 3y = 180

Subtracting 7:

3y = 180 - 7 = 173

Dividing by 3:

`y = (173)/(3)`

And:

`x = 7+ 2*(173)/(3)`

`x = (367)/(3)`
