Answer:
44
Step-by-step explanation:
use the order of operations
5 (3) 2 + 3 + 11. solve within parenthesis
15 × 2 + 3 + 11. multiply left to right
30 + 3 + 11. multiply left to right
33 + 11. add left to right
44. add
the order of operations is more commonly known as PEMDAS.
(parenthesis, exponents, multiply and divide, add and subtract)
If you are still confused there is a Brain Pop about PEMDAS. just search "order of operations" on the brain pop website
youll get 2and 3/4 then divide by 2 and you get 1.0375=2 and 3/80
hope this helps!

Complementary angles add up to 90°.
You are given one angle that is 63.6°.
Let's make the other angle "x".
63.6 + x = 90
To find x, all you have to do is subtract the other angle (63.6) from 90.
90 - 63.6 = 26.4
x = 26.4
The measure of the complementary angle is 26.4°.
