Question

In △ ABC, ∠A = 1000 and AB = AC. Find ∠B and ∠C.

Answer 1

Answer:

∠ B =  40

∠ C = 40

Step-by-step explanation:

let ∠ B = ∠ C = x  { ab = ac }

∠ a = 100

ATQ we've

∠ A + ∠ B +∠ C = 180 { Angle sum property of triangle }

100+x+x = 180

100+2x = 180

2x = 180-100

2x = 80

x = $\frac{80}{2}$

x = 40

∠ B =  40

∠ C = 40

pls correct the question make∠ A  = 100 not 1000
