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°

Answer: 1500 readers
explanation: all readers take up 100%
100/50=2
100% / 50 = 2%
2% x 50 = 100%
30 x 50 = 1500 readers
Let multiply by 35 both sides of the equation
35b+35*3/7=35*2/5
35b+15=14
There are all false
