Question

If two straight lines intersect and one angle is 30°, what are the other three angles?

A. 30°, 90°, 180°
B. 90°, 90°, 150°
C. 30°, 150°, 150°
D. 90°, 150°, 180°

PLEASE HELPPPPP!!! :(

Answer 1

C

Explanation:

Okay for problems like this when two lines intersect, the opposite angle is always the same.

If we know there are 360 degrees in total then we get the two 30 degree angles and add them up.

30+30=60

Then subtract

360-60=300

Then Divide:

300/2=150

So know you have two angles 150,150 and the other thirty degree angle

so the answer is: 30,150,150
