Answer:</u></h2>
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Answer:
$13.
Step-by-step explanation:
Let x represent money that Alison has.
We have been given that Leo has 7 times as much money as Alison had. So the amount of money that Leo has, would be
.
We are also told that Leo had $91, so we will equate
with 91 and solve for x as:

To solve for x, we will divide both sides by 7:


Therefore, Alison has $13.

Answer and explanation:
Perpendicular lines are lines that meet at 90 degrees/ right angle.
The question seems to be incomplete but I will explain what perpendicular lines are in the context of lines lll and mmm, with some assumptions about the lines.
Assume that line III is 30mm long and line mmm is 25mm long, we say that line III is perpendicular to line mmm if line III meets line mmm at 90 degrees as we see in the diagram attached.
