In the figure below, abc is a right triangle. a+b= 150 degrees, and c+d= 35 degrees. find x.
a. 150
b. 115
c. 85
d. 25

Alright, lets get started.

These two triangles ABC and ACD are jointly forming a polygon having 4 sides ABCD.

The sum of all internal angles of a polygon having 4 sides = 360

∠A + ∠B + ∠C + ∠D = 360

Plugging the values of each angle

Subtracting 275 from both sides

°

Hence the option is C. (85) : Answer
