Answer:
62
Step-by-step explanation:
Hi.
First, I am going to give you some definitions.This will help you do the problems.
-Complementary angles have a combined sum of 90.
- Supplementary angles have a combined sum of 180.
10. 40+50=90- so YES.
12. 159+20= 179.-so NO.
Make sure you learn the definitions properly next time!

Typically Geometry. But it depends on your level.
I answered the last post, the third option is correct
Answer:
-3
Step-by-step explanation:
Step 1: Write equation
-7.6(x - 1) = 7.3 - 7.4x
Step 2: Solve for <em>x</em>
<u>Distribute -7.6:</u> -7.6x + 7.6 = 7.3 - 7.4x
<u>Add 7.6x on both sides:</u> 7.6 = 7.3 + 0.2x
<u>Subtract 7.3 on both sides:</u> 0.3 = 0.2x
<u>Divide both sides by 0.2:</u> x = 1.5
Step 3: Find <em>-2x</em>
-2(1.5) = -3
