Answer:
-1 and 1
Step-by-step explanation:
These are the correct ratios trust me I've done them a thousand times 15: 7 and 15to7
Step-by-step explanation:
15*8= 120
120/2= 60
60*13= 780
So its B.
Answer:
C. Vertical angles are supplementary if both are right angles.
Step-by-step explanation:
You want to know the conditions when vertical angles are supplementary.
<h3>Supplementary angles</h3>
Two angles are supplementary when they total 180°.
<h3>Vertical angles</h3>
Vertical angles are formed when two lines cross. They share a vertex, but not a side. Their sides are opposite rays.
Vertical angles are always congruent.
<h3>Supplementary vertical angles</h3>
If x is the measure of one of two supplementary vertical angles, then we must have ...
x + x = 180°
2x = 180° . . . . . collect terms
x = 90° . . . . . . . divide by 2
Vertical angles will be supplementary if and only if they are both right angles.
