Question

Angle ABC is an isosceles triangle with AB=AC. If A = 30

Answer 1

Answer:

heya...

here is your answer....

Ans. ..

ABC is isosceles triangle..

the angle B = angle C

let angle. B = angle C = x

In triangle ABC,

angle A +angle B + angle c = 180 ...

( sum of the measure of all angles of triangle is 180 )

30 + x+x =180

30+2x =180

2x=180-30

x = 160/2

x=80

there fore

< B = < C =80

Answer 2

Answer:

hola..

here is your answer...

In triangle ABC is isosceles triangle.

AB = AC.. (1)

<A =30 • ... (given)

< B =

< A =< B = x

30+x+ = 180 ( sum of measure of the all angles of triangle are supllementry)

30+2x =180

2x =180-30

x =160/2

x = 80 •
