Question

I dont understand how to do this

Answer 1

The statement EF=2.GF (Option A) and the statement

$\frac{\sqrt{3} }{2} .EF=GE$ (Option C) are true for the ΔEFG.

What are trigonometric ratios?

The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.

Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.

Wow, sin 30°$=\frac{GF}{EF}$

⇒$\frac{1}{2} =\frac{GF}{EF}$

⇒EF=2.GF

and sin 60°$=\frac{GE}{EF}$

⇒$\frac{\sqrt{3} }{2} =\frac{GE}{EF}$

⇒$\frac{\sqrt{3} }{2} .EF=GE$

Therefore, the statement EF=2.GF (Option A) and the statement $\frac{\sqrt{3} }{2} .EF=GE$ (Option C) are true for the ΔEFG.
