Answer:
It's also 40° becuase it is a 90° angle. the mesuarement of the top is also the same
I hope it helps ;)
The first angle is 40 given
The second angle is 40 as well since its an isosceles triangle.
Sum of all 3 angles is180 for a triangle
therefore 40 + 40 + x = 180
solving, x = 180 - 40 - 40
x = 100
Thus the three angles in the triangle are 40, 40 & 100
