Find the 9

Find the missing angle in the triangle and then name triangle. Angles are: 95, 2x+15, x+3

Correct result:

x =  22.3333
A =  95 °
B =  59.6667 °
C =  25.3333 °

Solution:


95+(2x+15)+(x+3)=180

95+(2•x+15)+(x+3)=180

3x = 67

x = 673 ≈ 22.333333

Calculated by our simple equation calculator.
A=95=95∘
B=2⋅ x+15=2⋅ 22.3333+15=1793=59.6667∘=59∘40′
C=x+3=22.3333+3=763=25.3333∘=25∘20′
