Question

what is the answer of 1 ,2,3,4,5

Answer 1

In
1) x =40(base angles are same)
2) third angle =45(base angles are same)
we know that
sum of all angles in a triangle=180
45+x+45=180
90+x=180
x=180-90
x=90
3)x=50(base angles)
4)base angles are same
so let's take the down measurement as x
2x +100= 180
2x=180-100
2x=80
x=80/2
x=40
5)x=45

Answer 2

1)
solution:
since,it is isosceles triangle,
x=40 degree.

2)
solution:
x+45 degree+45degree= 180degree
x=90 degree.

3)
solution:
x=50 degree.

4)
solution:
x=40 degree.

5)
solution:
x=45degree.

I hope it will help u....
