Question

i need help asap pls !!!

Answer 1

Answer:

100°

Step-by-step explanation:

AB = AC (given)

Therefore, ∆ ABC is an isosceles triangle.

m<B=m< C= 40°

sum of the interior angles of a triangle= 180°

m<A+40°+40°=180°

m<A = 180°-80° = 100°

Answer 2

Answer:

< A is 100

Step-by-step explanation:

<B is 40 <C is also 40

so 40+40= 80 then you have to do 180-80. Which equals 100.
