Question

Please anwer these with brief explanation ..

Answer 1

1. as it is isosceles triangle,
x=y
sum of triangle is 180
x+y+70=180
x+x+70=180
2x. =110
x. =55
therefore, x=y=55

2.as it's an isosceles triangle
y=50
sum of triangle is 180
(180-x) +50+50=180
180-x. =80
x. =100
there fore x=100 and y=50

3. y=30(v.o.a)
as its an isosceles triangle
30+30+x=180
x. =120
therefore, x=120 and y=30

similarly you can make other three....
