Answer:
27.37 and 9.18
Step-by-step explanation:
(4)
Using the cosine ratio in the right triangle
cos64° =
=
( multiply both sides by x )
x × cos64° = 12 ( divide both sides by cos64° )
x =
≈ 27.37 ( to the nearest hundredth )
(5)
Using the sine ratio in the right triangle
sin35° =
=
( multiply both sides by 16 )
16 × sin35° = x , then
x ≈ 9.18 ( to the nearest hundredth )
Step-by-step explanation:
Is that the whole question or can you give me more information?
Answer:
I'm confused, can you show me a picture of the actual question?
I was thinking that the sequence was adding 2 everytime by the looks of it. There has to be a typo somewhere.
-3x+4=15
-3x=15-4
-3x=11
x= -11/3
4(-11/3)-y= -19
-44/3-y= -19
-y= -19+44/3 multiply by (-1)
y=19-44/3
y=19•3/3-44/3
y=57/3-44/3
y=13/3
(x,y)=(-11/3, 13/3)
