Question

The measure of two complementry angle are given as 2x + 10 degrees and 3x - 20.find the measure of each angle. Please send it by 1 minuit .my exam is going to start right now within 5 minuites

Answer 1

Sum of two complementary angles = 90
Here,
first angle = 2x + 10
second angle = 3x - 20
So, first angle + second angle = 90
(2x+10 ) + (3x - 20) = 90
5x - 10 = 90
5x = 90 +10
5x = 100
x = 20
So, first angle = 2x + 10 = 2 x 20 + 10 = 50
second angle = 3x - 20 = 3 x 20 - 20 = 60 - 20 = 40
