Answer:
m∠EDC = 4x+15 (vertically opposite angles are equal)
Step-by-step explanation:
Please find the attached document for explanation
Answer:
51
Step-by-step explanation:
(x) = 17 (One third of the total equals seventeen)
x = 17(3)
x = 51
Centroids create two segments.
The larger makes up 
of the total.
The smaller makes up of the total.
Answer:
6) Two angles are called supplementary when their measures add up to 180 degrees. For example, two right angles are supplementary angles.
7) When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
8) you have to plot the points on the graph and draw a line and label it with L at one point and M at another point.
9) x = 20
m < A = 65
m < B = 25
Step-by-step explanation:
9)
3x + 5 + 2x - 15 = 90
3x + 2x + 5 - 15 = 90
5x - 10 = 90
5x - 10 + 10 = 90 + 10
5x = 100
5 / 5x = 100 / 5
x = 20
A = 3x + 5
A = 3(20) + 5
A = 60 + 5
A = 65
B = 2x - 15
B = 2(20) - 15
B = 40 - 15
B = 25
