Question

Find m∠E to the nearest degree.

Answer 1

Answer: The value of  m∠E = 37°

Step-by-step explanation:

Since we have given that

ED = 8

EF = 10

DF = 6

We need to find the measure of m∠E .

$\sin E=\dfrac{DF}{EF}=\dfrac{opposite}{Adjacent}\\\\\sin E=\dfrac{6}{10}\\\\\sin E=\dfrac{3}{5}\\\\\sin E=0.6\\\\E=\sin^{-1}(0.6)\\\\E=36.86^\circ\\\\E=37^\circ$

Hence, m∠E = 37°

Answer 2

M<E = arcsin (opposite/hypotenuse)

m<E = arcsin (6/10)

Use the calculator:
m<E is estimated to be 37 degrees
