1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).

Sin x°=Opposite/Hypotenuse

Cos x°=Adjacent/Hypotenuse

2. The inverse of Sinx° is Cosec x°, then:

Cosec x°=1/Sin x°

3. The inverse of Cos x° is Sec x°, then:

Sec x°=1/Cos x°

4. Keeping this on mind, you have:

Cosc x°=Hypotenuse/Opposite

Sec x°=Hypotenuse/Adjacent

5. Therefore, the correct answer is:

The third option: Cosec x°=Hypotenuse/Opposite.

Find GE

Goryan [66]

Answer:

Option (B)

Step-by-step explanation:

From the picture attached,

To find the measure of segment GE,

Measure of HE = HG + GE and HE = HF + FE

HF + FE = HG + GE

By substituting the values of the given segments in the equation,

(3x - 129) + 4 = (13x - 993) + (3x - 185)

(13x - 993) + (3x - 185) - (3x - 129) = 4

Therefore, Option (B) will be the correct answer.
