Please I need help with questions 3-5 and it’s very hard and I’m struggling with it and if you need to see the picture big then

3.
m/_QOR + m/_ROS = 90 (because the two angels together make a right angle)

Substitute.

x + 5 + 2x + 7 = 90

3x + 12 = 90
-12 -12

subtract 12 from both sides

3x = 78

Divide each side by 3 to get x by itself

x = 26

4. those two angles in the picture are vertical, which means they're congruent.

with that in mind...the ray makes a right angle on one and the other, w, you dont know. so to get the whole angle you need to add both angles to get the whole thing so...

m/_w + 90 = 125

subtract 90 on both sides

m/_w = 35

Explain why a set of points that defines a plane cannot be collinear
USPshnik [31]

Answer:

Three non-collinear points determine a plane.

Step-by-step explanation:

This statement means that if you have three points not on one line, then only one specific plane can go through those points. The plane is determined by the three points because the points show you exactly where the plane is
