Question

HELPPPPPP SOLVE FOR X

Answer 1

x= 6

Explanation:

Straight line: is equaled to 180 degrees.

6y= 90 (90 divided by 6= 15), so y= 15

5x + 4y= 90 --> 5x + 4(15)= 90 --> 5x + 60= 90 --> 90 - 60= 30 --> 5x= 30 (30 divided by 5= 6), so x= 6

Answer 2

x = 6

Explanation:

These are supplementary angles.

This means that the angles add up to 180 degrees.

The first thing we can do is set 6y equal to 90, because the little red box means that is 90 degrees.

6y = 90

y = 15

Now that we have found y we can solve for x.

Plug in the y to the 5x + 4y

5x + 4(15)

5x + 60

We can set this equal to 90 again

5x + 60 = 90

5x = 30

x = 6

Therefore x is equal to 6.

I hope this helps!!
