Question

(Sat prep) find the value of x, 65 degrees and 75 degrees isosceles triangle.

Answer 1

• x = 40°

Explanation:

The triangle is not isosceles

The angles of the triangles are:

• 65°, 75° and x for both of the bigger and the smaller triangles

The interior angles of a triangle sum to 180

• x = 180° - (65° + 75°)
• x = 180° - 140°
• x = 40°
