Question

please ans this if anyone can help me immediately ​

Answer 1

Answer:

1st question answer is 60°.

Step-by-step explanation:

1st question answer.

Given in ∆ABC, AB=AC.

=> Angles opposite to the equal sides are equal.

Given angle B = 60° .

From above statement we can conclude that angle C is also equal to 60°.

And now, we already know that sum of all three angles in a triangle is 180°.

=> A+B+C = 180°

=> A+60°+60° = 180°

=> A= 60°

Hope it helps you.

All the very best.

Answer 2

1) option (a) 60° because

AB=AC then it's an isosceles triangle

so , Angle B=60° and angle A=60°

2) option (c) lesser because ,

the proof states that side opposite to greater side is larger so AB opposite angle C therefore

able B is lesser than angle C
