Question

Find the value of the unknown 'x'in the following triangles

A = x° B = 50 ° C =60 °​

Answer 1

Answer:

A= 70° because sum of all sides is 180° and sum of B and C=50°+60°=110°

So A=180°-110°=70°

Answer 2

Answer:

70°

Step-by-step explanation:

sum of the angles of a ∆= 180°

therefore, 180-(50+60)= 70°
