Question

The angles of a triangle are (x - 15),(2x + 35) and (2x + 10)". Find the angles​

Answer 1

Answer:

The sum of angles of a triangle is 180 degree

2x+x+2x+30=180

5x=150

x=30

So the angles are, 15,95,70 degress

Answer 2

Answer:

The sum of the angle of a triangle is 180°

Step-by-step explanation:

= (x - 15)° + ( 2x + 35)° +( 2x + 10°) = 180°

= x - 15 + 2x +35 + 2x + 10° = 180°

= 5x + 30 = 180°

= 5x = 180° - 30°

= 5x = 150°

x = 30°

Angles are:

x - 15 = 30 - 15°

2x + 35 = 2 ×30 + 35 = 95°

2x + 10 = 2× 30+ 10 = 70°
