Question

Which trig function should Sharlot use to find the measure of angle B ? C 1 А B 12 2 cosine 3 O O O pythagorean theorem sine y 4 -tangent 5 2 1 point A high rise apartment is on fire

Answer 1

Sine

Explanation:

We have that according to the graph the value of hypotenuse is the opposite of the right angle, therefore, its value is 12.

Angle B has two legs, the adjacent leg, which would be the CB side (Unknown) and the opposite leg, which would be the AC side, with a value of 5.

The trigonometric ratio that relates the opposite leg to the hypotenuse is the following:

`\sin \theta=\frac{\text{opposite}}{\text{hypotenuse}}`
