Question

In ΔUVW, the measure of ∠W=90°, WV = 40, UW = 9, and VU = 41. What is the value of the sine of ∠V to the nearest hundredth?

Answer 1

Answer: 0.22

Explanation:

sin C= Opposite/ Hypotenuse = 9/41 = 0.21950=0.22

Answer 2

∠V = 12.68°

Explanation:

In this question, we are tasked with calculating the value of the sine of ∠V to the nearest hundredth

Kindly note that since one of the angles in the triangle equals 90°, then we are dealing with a right-angled triangle.

Mathematically, to calculate the sine of an angle in a triangle, the ratio to use is

Sine of an angle = length of side facing angle/length of hypotenuse = opposite/Hypotenuse

From the diagram, we can see that the length of the opposite is 9 while the length of the hypotenuse is 41

Sine V = 9/41

V = arcsin (9/41)

V = arcsin (0.2195)

V = 12.68° to the nearest hundredth
