Answer:
The value of x is 84 and the remaining angles are: 76° and 86°
Step-by-step explanation:
Given three angles are
18
x-8
and
x+2
We have to find the angles and for that we have to find the value of x
As we know that the sum of internal angles of a triangle is 180°
So,
And the angles are:
x-8 = 84-8 = 76
x+2 = 84+2 = 86
Hence,
The value of x is 84 and the remaining angles are: 76° and 86°
