The statement EF=2.GF (Option A) and the statement
(Option C) are true for the ΔEFG.
<h3>What are trigonometric ratios?</h3>
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°
⇒
⇒EF=2.GF
and sin 60°

⇒
Therefore, the statement EF=2.GF (Option A) and the statement (Option C) are true for the ΔEFG.
