Question

In an isosceles triangle the base angle are equal and the vertex angle is twice of each
base angle. Find the measure of the angles of the triangle.
29. The numerator of a fraction is 4 less than the denominator. If 1 is added to both the
numerator and denominator, it becomes 1. Find the fraction.

Simplify: (2x + 5y) (3x + 4y) - (7x + 3y) (2x + y)
Or
(3x2 + 5x - 7) (x - 1) - (x2 - 2x + 3) (x + 4)

Answer 1

Answer:

q1. let the base angle be x

x + x + 2x =180 ( angle sum property )

4x = 180

x = 180/4

x = 45

angles are 45,45,90
