Question

The sum of two angles is 150" and their difference is 25", find all the angles of the triangle​

Answer 1

Answer:

30

Step-by-step explanation:

Let a,b,c be the angles of triangle

Given a+b=150&a-b=25

Add both

(a+b)+(a-b)=150+25

2a=175

a=87.5

b=150-87.5=62.5

c=180-(87.5+62.5)=180-150

=30

Angles of the triangle are 30,87.5,62.5
