Q1. If 3b and 2b are the two supplementary and angles
Find b​

Answer 1

Let the first angle be 3b

Then ,the second angle be 2b

A/q

=> 3b + 2b = 180° ( supplementary angle = 180° )

=> 5b = 180°

=> b = 180/5

=> b = 36°

Therefore, angle b is equal to 36°

Answer 2

$\bigstar$ EXPLAINATION $\bigstar$

• Given

3b and 2b are two supplementary angles

• Procedure

As 3b and 2b are supplementary angles,

Therefore,

3b + 2b = 180

5b = 180°

b = 36°

$\boxed{Answer\:is\:36°}$

• Extra Information

i) Sum of two complementary angles is 90°

ii) Sum of two supplementary angles is 180°

iii) All the angles in the triangle are supplementary angles

iv) The opposite angles of a rectangle are supplementary
