Answer: x= 80
Step-by-step explanation:
it’s an isoceles triangle so bottom 2 angles are 50
50+50= 100
180-100= x
1520 ÷ 10 = 152
1520 ÷ 20 = 76
1520 ÷ 40 = 38
There is none except for eleven and that is it

Equation: n + 5/16 = -1
Subtract 5/16 on both sides to bring it to the right side of the equation.
