Question

find the value of x.​

Answer 1

Answer: x= 40°

Step-by-step explanation:

Angle A+B+C=180° (by Angle sum property)

40°+x+30°+70°=180°

x+140°=180°

x=180°-140°

x=40°

Hence the value of x is 40°

Answer 2

Answer:

x+40°+30°+70°=180° (Angle Sum Property of a ∆)

x+140°=180°

x=180°-140°

x=40°
