Answer 2

Answer:

The value of x is 50°.

Step-by-step explanation:

Given : Three angles of a triangle are x+5, x+10 and x+15.

To find : The value of x ?

Solution :

The sum of three angles of a triangle is 180°.

Three angles of a triangle are x+5, x+10 and x+15.

So, (x+5)+(x+10)+(x+15)=180^\circ(x+5)+(x+10)+(x+15)=180

∘

3x+30=1803x+30=180

3x=180-303x=180−30

3x=150^\circ3x=150

∘

x=\frac{150}{3}x=

x=50^\circx=50

Substitute the value,

x+5=50+5=55

x+10=50+10=60

x+15=50+15=65

The angles are 55°,60°,65°.
