Answer:
20.5 , 30.4 , 5.3
Step-by-step explanation:
SOHCAHTOA
sinθ = opposite / hypotenuse
cosθ = adjacent / hypotenuse
tanθ = opposite / adjacent
10. tan64° = 42 / x ; x = 42 / tan64° ; x = 20.48476872
12. sin54° = BD / 20 ; BD = 20 * sin54° ; BD = 16.18033989 ;
tan28° = BD / DC ; DC = BD / tan28° ; DC = 30.43079344
13. tan51° = JL / 14 ; JL = 14 * tan51° ; JL = 17.28856019 ;
cos72° = KL / JL ; KL = JL * cos72° ; KL = 5.342458907

Cant help you for number 2 though. Hope this helps :)
Answer:
ASK you teacher very confusing
Answer: x = 49/8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 21/4 = 98
Step 2: Subtract 21/4 from both sides.
x + 21/4 = 21/4 = 91/8 - 21/4
x = 49/8
Hope this helps!
