An exterior angle of a triangle is 75 and one of its interioropposite angle is 35. Find the measure of the other interiorOpposite angle.?​

Answer»

Answer:

exterior angle = sum of 2 opposite interior angles

let the unknown angle is Z

then

75= 35+z

by transferring 35 towards left

75 - 35 = z

40⁰= z

therefore the VALUE of z is 40 so angle is ALSO 40⁰
