What is the value of x in the figure below?
70°
xo
115°
A 45°
B. 550
C. 57.59
D. 22.50

Answer:
A. 45°
Step-by-step explanation:
By exterior angle theorem:
x + 70° = 115°
x = 115° - 70°
x = 45°
Answer:
x= 45°
Step-by-step explanation:
triangles degrees all together are always 180°
x≠180°
a straight line is also 180°
180°-115°= 65°
70°+65°= 135°
180°-135°= 45°
