If the angles are vertical, they must be equal.
If the angles are supplementary, then they add up to 180 degrees.
If each angles is x (since they are equal)
then
2x=180, or
x=90 °
The angles are each 90 °
It is D. it has a negative slope and is not as steep as -3
We know that
<span>1ft = 12in
then the scale is:
6 feet to 2 inches,
or
72 inches to 2 inches,
that is a scale:
72:2
equivalent to:
36:1
or
108:3</span>
5(x+(x+1)+(x+2))=150
5(3x+3)=150
15x+15=150
15x=135
x=9
Your three consecutive integers are 9, 10, and 11.
