If you have 7 striped ties and 21 solid ties and they're asking for the ratio of striped to solid, then you would write it as

7:21

And if you want it simplified, you would divide 7 by 7 and 21 by 7. So,

7/7= 1

21/7= 3

The answer is 1:3

Answer: x = 70, y = 110, z = 85

Step-by-step explanation:

If BE = CD, then using corresponding angles (are equal), x = 70

If x = 70, then 70+y = 180 (angles on a straight line)

y = 110

And z = 85 (corresponding angles again): angle ABE = angle ACD

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

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 $\triangle FED$

$F+E+D=273$
