Answer:

the answer is 96°

Step-by-step explanation:

it is an isosceles triangle as it's 2 sides are equal.

for an isosceles triangle, the angles made by the equal sides with the third side are equal.

and the sum of all angles in a triangle = 180°

42 + 42 + x = 180

x = 180 - 84

X = 96°

I = / r where I = current and r = resistance

80 = k / 50 so
k = 400

so we have I = 400/r

when r = 40
I = 400/40 = 10 amps
