Answer:
34
Step-by-step explanation:
if you add 90+56 you get 146 and then 180-146=34
a = 34°
1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.
2. This means that a + 90 + 56 = 180.
3. (Solving equation above).
Step 1: Simplify both sides of the equation.
Step 2: Subtract 146 from both sides.
Step 3: Check if solution is correct.
Therefore, a = 34°.

-64
a(b - c)
a = -8
b = 12
c = 4
So, you'd plug in those numbers:
-8(12 - 4)
You'd start within the parenthesis's, so:
(12 - 4), which equals (8)
-8(8)
= -64
