Answer:

x = 8.8

Step-by-step explanation:

To solve this you need the Law of sines

sin A / a = sin B / b = sin C / c

a, b, c are the sides opposite to angles A, B and C respectively

Applied to the given triangle we have one side given, the opposite angle to be found.

sin 28 / x = sin (180 - 28 - 126) / 8.2
sin 28 / x = sin 26 / 8.2
x = 8.2 sin 28 / sin 26
x = 8.8 (rounded)

Answer:

Irrational.

Step-by-step explanation:

Rational means that it is a whole number and can be written as a fraction. That doesn't apply for square rooted numbers. So, $\sqrt{62}$ is irrational.
