Answer 1

Answer:

$4552520 \times \div 25111$

Answer 2

Answer:

Step-by-step explanation:

Base angles will be same because it is an isosceles triangle

Base angle 1 = B

Base angle 2 = B

Vertex angle = 2B

According to Angle Sum Property:

B+B+2B = 180

4B = 180

B= 180/4

B= 45

Therefore base angles are 45 degree each and vertex angle is 90 degree.
