Question

To the nearest hundredth, what is the value of x?

Answer 1

1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:

sin53° = x/45 => x = sin53° · 45 ≈35.94

2. We already have one out of two legs of the triangle and one acute angle so we know that:

tan27° = 48/x => x = 48/tan27° ≈ 94.21

Answer 2

The value of x in the first right angle triangle is 27.08.

The value of x in the second right angle triangle is 24.46.

What is the value of x?

In order to determine the value of x in the first triangle, cos would be used.

Cos 53 = opposite / hypotenuse

Cos 53 = x / 45

0.7071 = x /45

x = 45 x 0.6018

x = 27.08

In order to determine the value of x in the second triangle, tan would be used.

Tan 27 = opposite / adjacent

Tan 27 = x / 48

x = 0.5095 x 48

x = 24.46
