1) Given that the measure of Angle 2 = 115 degrees and the measure of Angle 8 = 115 degrees, is line m parallel to line p?
Answer:
YES
Step-by-step explanation:
When a transversal cuts two parallel lines, the alternate interior angles are congruent. So, for two lines to be parallel, their alternate interior angles has to be equal.
Angle 2 and angle 8 are alternate interior angles. They both measure 115°. Since these alternate interior angles are congruent, therefore, line m is parallel to line p.

When a person 6 feet tall casts a shadow
10 feet long, how tall is a nearby tree
which casts a shadow of 45 feet?
Answer:
75 feet
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
Proportion
6 feet man/10 feet shadow = x (tree) / 45 feet (shadow)
6/10 = x /45 Cross multiply
10x = 45*6
10x = 270
x = 270/10
x = 27
The tree is 27 feet long

Gabriel is 12 years old, and his younger brother Elias is 2 years old.
How old will each of them be when Gabriel is twice as old as Elias?
Gabriel will be 20, Elias will be 10
We can use an equation to map out and solve for each age.
Years gone by = x
12+x=2(2+x)
12+x=4+2x
x=8
12+8=20, 2+8 =10

I'm Really confused on this please help.
Write three points (x, y) that exist on the line.
Answer:
3 points on the line - (.5,3) (1,2) (1.5,1)
Step-by-step explanation:
y = -2x + 4 (1.5,1)
1 = -2x + 4 subtract 4 from each side
-3 = -2x divide each side by -2
1.5 = x
y = -2x + 4 (1,2)
2 = -2x + 4 subtract 4 from each side
-2 = -2x divide each side by -2
1 = x
y = -2x + 4 (.5,3)
3 = -2x + 4 subtract 4 from each side
-1 = -2x divide each side by -2
.5 = x
Answer:
(1,2) (2,0) (3,-2)
Step-by-step explanation:
What I did to get those is plug in the numbers 1, 2, and 3 as values of X.
-2(1)+4
that gave me 2 as the Y value and now we have the coordinate (1,2).
-2(2)+4
that gave me 0 as the Y value and now we have the coordinate (2,0).
-2(3)+4
that gave me -2 as the Y value and now we have the coordinate (3,-2).
