Answer:
28
Step-by-step explanation:
We can see that all the angles are inside of a triangle and the sum of the interior angle of the triangle is 180 degrees.
Knowing this, we know that the sum of all the angles present is 180 degrees.
1st angle can be seen as 90 degrees, 2nd angle is x+6 and the 3rd is 2x.
The sum can be written as ( 90 + x + 6 + 2x ) and this equals to 180 degrees.
90 + x + 6 + 2x = 180
96 + 3x = 180
( subtract 96 on both sides )
3x = 180 - 96
3x = 84
( divide by 3 on both sides )
x = 84 / 3
x = 28
