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 $\triangle FED$

$F+E+D=273$

What is the slope of the line in the graph?

Sedbober [7]

<h3>Answer: 1</h3>

========================================================

Explanation:

Pick any two points you want from the blue line. I'll pick (0,1) and (1,2)

Apply the slope formula to those points

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

m = (2-1)/(1-0)

m = 1/1

m = 1

The slope is 1.

Notice how if we're at (0,1), then we move up 1 and over to the right 1 to arrive at (1,2).

slope = rise/run = 1/1

rise = 1, run = 1
