Congruent Parts of a Congruent Triangle are Congruent
∠B ≅ ∠E
AB <span>≅ DE
BC </span><span>≅ EF
AB = 20
BC = 24
EF = 6
DE = x
20/24 = x/6
Solve for x, cross multiply
24(x) = 20(6)
24x = 120
24x/24 = 120/24
x = 120/24
x = 5
x = 5, or A is your answer

Answer:
73 and -23 hope this helped hon :)
Step-by-step explanation:
y=-8x+9
plug in -8
y=-8(-8)+9
y=64+9
y=73
y=-8x+9
plug in 4
y=-8(4)+9
y=-32+9
y=-23
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Answer:
D) collinearity
Step-by-step explanation:
Collinearity occurs when a few of the independent variables are related or match up. Collinearity increases the large proportion the variance of an estimated regression coefficient which leads to certain regression coefficient having wrong signs. It is used to explain the relationship between two variables.
