Answer 1

Answer:

Your question is solved above

Answer 2

Answer: In an isosceles triangle, 2 vertical angles are equal.

So, let the base angle = x degrees

And the vertical angles= x+18 degrees

Now by using angle sum property,

x+ x+18+x+18 = 180 degree (We have written x+18 two times bcoz they are                          two same angles)

3x +36 degree = 180 degree

3x= 180-36 degree (Shifting 36 to right side)

3x= 144

x= 144/3 (Shifting 3 to right side)

x= 48

Base angle= x=48 degrees

Vertical angles= x+18= 48+18=  66 degrees

So, base angle= 48 degrees

Hope it helps!!
