Answer: 39.2Check out the attached image
============================================================
Explanation:
Draw out the triangle or use the diagram provided by your teacher. It should look something similar to what I've attached.
Let m = length of side XZ
We are given that
angle Y = 75 degrees
angle Z = 67 degrees
which are the green angles shown in the diagram
Use the fact that the three angles (X,Y,Z) add to 180 degrees to find angle X
X+Y+Z = 180
X+75+67 = 180
X+142 = 180
X+142-142 = 180-142
X = 38
Now use the law of sines to find m
sin(X)/YZ = sin(Y)/XZ
sin(38)/25 = sin(75)/m
m*sin(38) = 25*sin(75)
m = 25*sin(75)/sin(38)
m = 39.22309 <<<--- make sure your calculator is in degree mode
m =
39.2So
XZ is roughly 39.2 feet in length
Answer:
B because the line crosses the y axis at 4 and the slope will be -1 because the line is going downhill which therefore makes it negative
hope it helps:)
Step-by-step explanation:
Sorry I don't see a picture. But...
If they add up to 90 degrees, they are complimentary
If they add up to 180 degrees ( a straight line) they are supplementary.
If they are vertical, they will be on either side, like two v's ><
