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.
Rope(r)
By using Pythagoras:
r^2 = 8^2 + 6^2
r^2 = 64 + 36
r^2 = 100
r = square root of 100
r = 100ft
The answer is C. 100ft
Answer: The space given up by the students is 1/4 of the total space.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em> Students must give up half of the exhibit space to the other school.</em> So, we have to divide 5/10 by 2.
5/10 ÷ 2/1 = (5x1 ) / (10 x2 ) = 5 /20
Simplified (by 5) = 1 /4
The space given up by the students is 1/4 of the total space.

Answer: perimeter= 2m+22 units
Step-by-step explanation:
length= 2m+1
width= 10-m
p=2(l+b)= 2(2m+1+10-m)
p=2(m+11)
p=2m+22 units
The point-slope form:
- given point
- given slope
The standard form:
<em>use distributive property</em>
<em>add 
to both sides</em>
<em>subtract 
from both sides</em>
<em>change the signs</em>
