Answer: x=31
Step-by-step explanation:
(3x+25)+2x=180
5x+25=180
5x=155
x=31
From the first picture, the triangle can be redrawn. It is an isosceles triangle.
The base angles of an isosceles triangle are angle. Hence, angle A = angle C = 56°.
Note that: angle À + angle B + angle C = 180° (sum of angles in a triangle)
56 + B + 56 = 180°
B + 112° = 180°
B = 180° - 112°
B = 68°
