x = 8.3
Step-by-step explanation:
Triangles always equal to 180 degrees when taking about angles.
The equation would be:
30+(11x+5)+(-5+7x)= 180
add like variables:
30+5-5 = 30
11x+7x = 18x
put them into an equation:
18x +30= 180
cancel out:
18x+30=180
-30 -30
18x = 150
Divide:
÷ 18 ÷18
This is an estimate as the answer in the calculator would be very long.
