Answer: hypotenuse=16
Step-by-step explanation:
First, you need to know the concept of a special triangle 30-60-90. The corresponding ratio of each side is 1-√3-2. Basically means, the shortest side is 1, the other longer leg is √3, the hypotenuse is 2. You can also refer to the attachment below
For this question, given the shortest side is 8, and asked to find the hypotenuse.
Short side:hypotenuse=1:2
8:hypotenuse=1:2
hypotenuse=16
Hope this helps!! :)

Answer:
The Proof is given below.
Step-by-step explanation:
Given:
bisect ∠ EHG.i.e
∴ ∠EHF ≅ ∠ GHF
To Prove:
Proof:
In Δ EHF and Δ GHF
EH ≅ GH ………............{Given}
∠ EHF ≅ ∠ GHF …………..{EF bisect ∠ EHG as given above}
HF ≅ HF ………............{Reflexive Property}
Δ EHF ≅ Δ GHF …................{ By Side-Angle-Side test}
∴ EF ≅ GF........{corresponding parts of congruent triangles (c.p.c.t).}
....... PROVED
