The answer X= -10 y= -5
Hope this is helpful
Cosine is adjacent/hypotenuse
The adjacent side to angle F is 60, and the hypotenuse is 61
Therfore, C) 60/61 would be the correct choice
hope this helps:)
Answer: 1) The missing length is 40. 2) The missing side is 30 .
Step-by-step explanation:
1) 9^2 + b^2 = 41^2
81 + b^2 = 1681
-81 -81
b^2 = 1600
b= 40
2) 24^2 + 18^2 = c^2
576 + 324 = c^2
900 =c^2
c= 30
First you expand the brackets, so
36 + 6y = 9 - 3y
Then you get all the y's on one side
+ 3y
36 + 9y = 9
- 36
9y = 9
Then you divide by 9 to get y by itself
y = 1
You add all of them up and then do decided by 10 because there are 10 number in there it’s 10.1
