Answer 1

i think 70 degrees

becuase all triangles and up to 180 degrees

70+ 70(becuase two sides are equal ) and +40 equals 180 degrees.. i think 70 is the answer(not sure i'm not a pro when it comes to maths... but that my final answer.

Answer 2

Explanation:

So this is an isosceles triangle so the other angle must be x too.

So:

x+x+40 = 180

2x+40 = 180

2x = 140

x = 70
