You will need 7 because 150 divided by 20 is 7
8 - 3 = 5 Slope formula numerator
2 - 0 = 2 Slope formula denominator
5/2 = 2.5
I THINK the answer is compatible numbers.............. but I'm pretty sure it is compatible numbers
Since you are given that the triangle are similar, by definition of similar, we know that corresponding angles are congruent and corresponding sides are proportional.
The ORDER of the similarity statement is paramount.
Triangle ABC is similar to triangle EDC means that:
Angle A = Angle E
Angle B = Angle D
Angle C = Angle C
Angle B = 62 degrees so Angle D = 62 degrees.
