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


Answer:
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
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.
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
