please solve 1 and 2

Answer 1

refer the attachment for the answer to the 1st question




2nd question.
we know that in an isosceles triangle,2 angles are equal.

one of the equal angles = 65°
the other equal angle will also be 65° because in an isosceles triangle,2 angles are equal.
therefore,

let the third angle be x
sum of interior angles of a triangle=180°
we have,

65+65+x=180
130+x=180
x=180-130
x=50

2nd angle is 65°
3rd is 50°
