Answer:

The slope is -2/25.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(14-18)/(30-(-20))

m=-4/(30+20)

m=-4/50

simplify

m=-2/25

Triangle ABC is similar to triangle FED, find the measure of x. A. X = 9 B. X = 11 C. X = 110 D. X = 231
just olya [345]

Answer:

A+B+C=130

F+E+D=273

Step-by-step explanation:

From the question we are told that:

Dimension of ABC

A=9

B=11

C=110

Dimension of FED

D=231

Generally the equation for the similar triangles is mathematically given by

\frac{A}{F}=\frac{B}{E}=\frac{C}{D}

Therefore solving for F

\frac{9}{F}=\frac{110}{231}

F=\frac{9*231}{110}

F=18.9

Therefore solving for E

\frac{11}{E}=\frac{110}{231}

E=\frac{11*231}{110}

E=23.1

Measure of \triangle ABC

A+B+C=130

Measure of \triangle FED

F+E+D=273
