Question

for each of the following, the given angle is the base of angle of an isosceles triangle. find the third angle of the triangle. 79⁰​

Answer 1

Answer:

Step-by-step explanation:

2(x^2-x) = 3

2x^2 -2x= 3

2x^2-2x-3 = 0

Here,

a = 2 b= -2 c = -3

b^2 -4ac = D

= (-2)^2 - 4(2)(-3)

=4 + 24

= 28

Since D > 0 this equation has real but distinct roots.

This is quadratic equation.
