In δefg , what is the approximate length of ef if the measure of angle g is 50° and fg is 10 cm?

Hey again, you can use trigonometric ratios for this one. You are trying to find the side length opposite of angle G, when you have the adjacent side length value known. You can use TOA, or tan((opposite/adjacent)) . Tan(50) = x/10 

X=  11.92 cm
