Answer:
sin θ = 24/25.
Step-by-step explanation:
Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.
So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)
= sqrt 576
= 24 .
Therefore sin θ = 24/25.
(2x-2)+(15x+29)=180
17x+27=180
17x=180-27
17x=153
x=153/17 = 9
Answer is D
Answer:
-880.75
Step-by-step explanation:
Subtract 912 from 20.25 first then add 11.
The answer is: [D]: "0.815" .

Answer: x=9,y=-1/3
Step-by-step explanation: This is for Q. 16
Rearrange terms to line up properly.
x-3y=10
x+3y=8
eliminate y terms
x=10
x=8 now add all like terms, remember it's a given that there's a one in
front of a variable.
2x=18 solve for x
x=9 now plug in the nine into one of the original eq.s and solve for y
9+3y=8
3y=-1
y=-1/3 always check solutions in both eq.s to vertify. they both work
