Question

1) A 60. 70' then find angle ZC is
a) 80
b) 90
c) 50
d) 100
​

Answer 1

Answer:

c) 50°

Step-by-step explanation:

According to the angle sum property of triangle, the sum of all three angles is 180°.

Given, angle A = 60°, angle B = 70°

=> 60° + 70° + angle C = 180°

=> 130° + angle C = 180°

=> angle C = 180° - 130°

=> angle C = 50°
