Find the 9

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

Result

x =  22.333
A =  95 °
B =  59.666 °
C =  25.333 °

Solution:


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

3x = 67

x = 673 ≈ 22.333333

Calculated by our simple equation calculator.
A=95=95∘A=95=95 ^\circ
B=2⋅ x+15=2⋅ 22.3333+15=59.666=59.666∘=59∘39′58"B=2 \cdot \ x+15=2 \cdot \ 22.3333+15=59.666=59.666 ^\circ =59^\circ 39'58"
C=x+3=22.3333+3=25.333=25.333∘=25∘19′59"C=x+3=22.3333+3=25.333=25.333 ^\circ =25^\circ 19'59"
