Plzzzzzz helppppp asappppp ****willl mark brainliest ****

Answer 1

So the 30-60-90 triangle is considered one of the "special triangles". If the short leg is x, then the hypotenuse is 2x and the long leg is x√3.

Since our short leg is 5, the hypotenuse (DE) is 10 and the long leg (DF) is 5√3.

Answer 2

No brainliest needed for this one; it's the biggest cliche in trig.

The 30/60/90 is one of the two right triangles to memorize. It's half an equilateral triangle and the sides come in the ratio $1: \sqrt{3}:2$

So if the small side, EF=5, the sides are

$EF:DF:DE=5:5 \sqrt{3}:10$
