In ΔEFG, the measure of ∠G=90°, the measure of ∠E=20°, and GE = 75 feet. Find the length of EF to the nearest tenth of a foot.
1 answer:
Answer:80 feet
Step-by-step explanation:
Sum of < in a triangle is 180°
<G + <E + <F=180°
90 + 20 + < F = 110
< F = 70°
Using sine rule
sin G\EF = sin F\EG
sin90°\EF = sin70°\75
EF = 75sin90°\sin70°
= 79.81
=80 to the nearest tenth feet.

Answer:
√134
Step-by-step explanation:
Solve for the top line first,
√(5²+3²)
= √34
then for the dotted line,
√(10²+(√34)²)
= √134
