Answers

Answer 1
Answer:

Answer:

x = .58

Step-by-step explanation:

5.7 + 4.8x = 8.5

4.8x = 8.5 - 5.7

4.8x = 2.8

x = 2.8 / 4.8 = .58

Question 5Two similar triangles are shown in the diagram below, where
AABC - ADEF.
Based on the dimensions in the diagram, what is the
perimeter of AABC?
A-9 in.
B-10 in.
C-9.5 in.
D-10.5 in.

Answers

Answer:

Perimeter of ΔABC is 9.5 in.

Step-by-step explanation:

Given:

ΔABC \sim ΔDEF

DE = 6 in.

EF = 5.25 in.

DF = 3 in.

AB = 4 in.

We need to find the Perimeter of ΔABC.

Solution:

First we will find the sides of ΔABC.

Now By Triangle similarity property which states that:

"When two triangles are similar the the ratio of their corresponding sides are equal."

From Above property we can say that;

(AB)/(DE) =(BC)/(EF)=(AC)/(DF)\n\n(4)/(6)=(BC)/(5.25)=(AC)/(3)

Now we will find BC and AC

(4)/(6)=(BC)/(5.25)\n\nBC = (4*5.25)/(6)= 3.5 \ in

Also;

(4)/(6)=(AC)/(3)\n\nAC = (4*3)/(6) = 2 \ in

Now In ΔABC

AB = 4 in

BC = 3.5 in

AC =2 in.

Now Perimeter of ΔABC can be calculated as sum of all sides.

Perimeter of ΔABC =  AB +BC +AC = 4 + 3.5 + 2 = 9.5 in

Hence Perimeter of ΔABC is 9.5 in.

Remember, one whole circle is 360 degrees. This means that the side that looks to be the same as 43 degrees is 43 degrees. The side that looks the same as (6x+5) should be (6x+5).

Now just set up your equation like this and solve:

43+43+6x+5+6x+5=360
