Step-by-step explanation:
i took the quiz it was a quiz for me but i dont know for you
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
Hope this helps! I can resubmit if my hand writing is too bad.
For this question you should know:
1/2 = 5/10
and
4/5 = 8/10
so you can see 8/10 is greater than 5/10 so the answer is no
4/5 is greater than 1/2 :)))
i hope this is helpful
have a nice day
Answer:
x = 50
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 2 given angles in the lower triangle and subtract from 180 to find the third angle
third angle = 180° - (65 + 65)° = 180° - 130° = 50°
x = third angle = 50 ( vertical angles )
