First, we should figure out an equation and take note that we are dealing with complementary angles (angles that add up to 90 degrees)
Your equation:
(2x + 1) + (x - 7) = 90
Now solve!
====================================================================
SOLVING...
(2x + 1) + (x - 7) = 90
Simplify and combine like terms
2x + 1 + x −7 =
90
2x + 1 + x +
−7
=
90
(2x + x)
+
(1 + −7)
=
90
3x + −6
=
90
Add 6 to each side
3x
− 6
+ 6
=
90
+
6
3x = 96
Divide each side by 3
3x ÷ 3 = 96 ÷ 3
x = 32
