We have an angle, a hypotenuse - the ladder length - and we're looking for the opposite side......the sine seems the way to go, here.....
sin 65 = opp / 20 multiply both sides by 20
20 sin 65 = opp = about 18.13 ft up the wall
Answer:
(-2,3)
Step-by-step explanation:
Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.
7-9=-2
x=-2
Then all you have to do is put it into ordered pairs.
(x,y)
(-2,3)
Answer:
^3sqrt(-27), ^3sqrt(-8), 0, ^3sqrt(8), ^3sqrt(27), sqrt(10), 6, 8
Step-by-step explanation:
You just need to convert these to decimals to figure it out.
In our case
^3sqrt(-27) = -3
^3sqrt(-8) = -2
^3sqrt(8) = 2
^3sqrt(27) = 3
sqrt(10) = 3.16
So...
-3, -2, 0, 2, 3, 3.16, 6, 8
