Question

In right triangle EFG , what is the approximate length of side EF if the measure of angle G is 50 degrees and side FG is 10cm?

Answer 1

From part C, the estimated length of side FH is 5.8 units. Since FG and FH have equal lengths, the length of FG is also about 5.8 units.

Explanation:

Answer 2

we know that

Triangle EFG is a right triangle
then
tan G=EF/FG--------> EF=FG*tan G
FG=10 cm
G=50°
so
EF=10*tan 50°--------> EF=11.92 cm

the answer is
EF=11.92 cm
