Question

* Each base angle of an inceles triangle is 15more than its vertical angle. Find each angle of the
ical angle of an isosceles triangle
12 in the given figure, AB CD. The line segments BC and AD intersect at 0. Show that :z=x+y​

Answer 1

Step-by-step explanation:

Let vertical angle of the isosceles triangle = x°

∴ Each base angle = x + 15°

X + 15° + x + 15° + x° = 180°

(Sum of angles of a triangle)

⇒ 3x + 30° = 180°

⇒ 3x = 180° - 30° = 150°

∴ x = 150°/3 = 50°

Hence vertical angle = 50°

and each base angle = 50° + 15° = 65
