Question

In the given figure

the side BC of ΔABC is

produced to a point D. Find x.​

Answer 1

Answer:

x = 60°

∠A = x = 60°

∠B = (x + 10) = 70°

Step-by-step explanation:

Exterior angle = sum of remote angles

∠ACD = ∠ABC + ∠BAC

130° = (x+10) + x

130 = 2x + 10

x = 60°

Answer 2

Answer:

x = 60°

∠A = x = 60°

∠B = (x + 10) = 70°

Step-by-step explanation:

Exterior angle = sum of remote angles

∠ACD = ∠ABC + ∠BAC

130° = (x+10) + x

130 = 2x + 10

x = 60°
