Question

if the value is 60° C value 70 degree d value is X and find the value of a​

Answer 1

Step-by-step explanation:

given : cC= 60°, B= 70° and find x=?

solution : angle sum property of a triangle

C + B + A = 180°

60°+ 70°+ A= 180°

A = 180°-130°

A = 50°

Answer 2

Answer:

In ∆ PQR

P + Q+ R = 180° ( By angle sum property of triangle)

60°+70°+x = 180°

130°+ x = 180°

x = 180°- 130°

x = 50°
