Answer:

x = 56°

Step-by-step explanation:

The triangle given has two equal sides, therefore, it is an isosceles triangle. And isosceles triangle has two equal base angles which are opposite to each of the equal sides.

Therefore:

2(62°) + x = 180° (sum of triangle)

Solve for x

124° + x = 180°

x = 180° - 124°

x = 56°

The quadratic formula is x= -b +/- √b²-4ac / 2a

In this problem,

a=6
b=4
c=-3

Now, we can plug this into the formula:

x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6

So,

x= -2 + √22 / 6
x= -2 - √22 / 6
