Answer:
multiple choice or what?
Step-by-step explanation:
could use 2l+2w, that would be perimiter. L=12, so 12+12+2w.
Answer:
1. RQ
2. R, Y and V
3. T
4. No
Step-by-step explanation:
If we imagine a plane as a rectangle, we can easily see that planes RSTQ and RVUQ intersect in line RQ. Basically, if two planes intersect each other, that intersection is always a line.
Collinear points lie on the same line. Every two points make a line, so the third one also needs to lie along that line. On the diagram, R, Y and V are the only three points on the same line.
From the diagram, we can infer that QT and TX intersect in point T. Additionally, every two lines intersect in a point (of course, unless they're parallel).
Coplanar points lie in the same plane. Three points are enough to define a plane. Whichever three points (R, Q, W and U) we choose we'll have a plane, but the fourth point won't lie in it. This means they are not coplanar.
56 is the slope
and -4 is the y intercept
so you first graph 0,-4
then use the slope and move 56 units up and one to the right
Answer:
25 degrees
Step-by-step explanation:
By the Law of Sines,
(sin R)/20 = (sin(50°))/(36)
sin R = (20sin(50°))/36
R = arcsin((20sin(50°))/36), which is about 25 degrees.
