Find the 9

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

Correct answer:

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

Step-by-step explanation:

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

95+(2•x+15)+(x+3)=180

3x = 67

x = 67/3 ≈ 22.333333

Our simple equation calculator calculates it.

$A=95=95\text{°}$

$B=2\cdot x+15=2\cdot 22.3333+15=59.6667\text{°}=59\mathrm{°}40^{\mathrm{\prime }}$

$C=x+3=22.3333+3=25.3333\text{°}=25\mathrm{°}20^{\mathrm{\prime }}$
