Answer:

60° and 30°

Step-by-step explanation:

I'm going to assume you mean complementary angles.

Complementary angles are angles that form 90° or a right angle

From the question, it is saying that

(5x) +(4x-18) = 90

To work out x, solve the equation

9x-18 = 90

9x = 108

x = 12

Therefore the angle of 5x is 5x12 or 60° and the angle of (4x-18) is going to be 4x12-18 = 30°

In this situation the answer is automatically 1

Check:

1/2(1)+7=1+14/2?

7 1/2= 7 1/2 ✔️

Jill sold half of her comic books then bought 16 more, she now has 36. With how many did she begin with? Break it down please
marusya05 [52]
A: 40

Let’s do this problem backwards.


TOTAL BOOKS RN: 36

1)
“Jill... then bought 16 more...”

36 - 16 = 20

After subtracting that amount, we would end up with half of the books Jill DID NOT sell.

2)
2 • 20 = 40

At this point, we multiplied amount of books she had after she sold half of her comic books by the reciprocal of 1/2

And now you have your answer!
