Yes, both angles are acute because all complementary angles are acute.
You must first attach the problems with your question.
<u>4</u> = <u>x
</u> 18 90
(4 * 90) / 18 = 20
<u>
</u> x = 20 So Angie can run 20 miles in 90 minutes!<u>

Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°
Answer:
Make N alone
There is an 8 so we subtract 8 from both sides so the equation is still equal
-4 - 8 = -12
Because we are subtracting N it is positive
N = 12
8 - 12 = -4
