(You copied 'upper left' twice, and you left out 'lower right'.
But we know what you mean.)
If those are the corners of the wall, then they're ALL in the plane of
the wall (coplanar with it).
For right triangles, use SOH CAH TOA.
Given angle is 27, given sides are 'x' and 20.
Which sides are given, opposite, adjacent, or hypotenuse?
opposite is across from angle(27) -----> unknown
adjacent is leg next to or touching the angle(27) -----> 'x'
hypotenuse is side across from right angle -----> 20
which trig ratio uses adjacent and hypotenuse?
CAH has both A for adjacent and H for hypotenuse.
Therefore use the cosine ratio.
Answer:
y= x squared.
Step-by-step explanation:
When graphed, the parabola only has an x-intercept at (0,0). Since a root is another word for an x-intercept, it only has one root.
I hope this helps, and I hope you have a good day.
Answer:
it is 0 because cosine is the x and sine is the y. Sin is 1 and cos is 0
