Find the perimeter of ABHG

Mathematics
1 answer:
nadezda [96]3 years ago
6 0

Answer:

  • 124 in

Step-by-step explanation:

Use ratios to find x and y, then find AB and GH, them sum up the lengths.

<u>Find x:</u>

  • 12/15 = x/10
  • x = 12*10/15
  • x = 8 in

<u>Find y:</u>

  • 12/15 = 16/y
  • y = 15*16/12
  • y = 20 in

<u>Find AB:</u>

  • y - 14 = 20 - 14 = 6 in

<u>Find GH:</u>

  • 5x - 3 = 5*8 - 3 = 37 in

<u>Find the perimeter:</u>

  • P = 6 + 15 + 20 + 10 + 37 + 8 + 16 + 12 = 124 in

Kayla wants to find the width, AB, of a river. She walks along the edge of the river 65 ft and marks point C. Then she walks 25
AlladinOne [14]

Answer:

Part A) The triangles ABC and EDC are similar by AAA, because the three internal angles are equal in both triangles

Part B) The width of the river is about 39\ ft

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

Part A) we know that

In this problem , triangles ABC and CDE are similar by AAA, because its corresponding angles are congruent

so

m<DCE=m<ACB -----> by vertical angles  

m<EDC=m<ABC -----> is a right angle

m<DEC=m<CAB -----> the sum of the internal angles must be equal to 180 degrees

Part B) we know that

The triangles ABC and EDC are similar -------> see Part A

therefore

\frac{BC}{DC}=\frac{AB}{DE}

substitute the values and solve for AB

\frac{65}{25}=\frac{AB}{15}

AB=15*(\frac{65}{25})=39\ ft

PLEASE HELP

<u>Answer:</u>

$593.26

<u>Step-by-step explanation:</u>

We know that the price of the laptop is $2500 and each year its resale value decreases by 25%. It means that 100 - 25 = 75% of the value is retained every year for the resale.

So, the resale value for 1st year = \frac{75}{100} *2500 = $1875

for 2nd year =  \frac{75}{100} *1875 = $1406.25

for 3rd year =  \frac{75}{100} *1406.25 = $1054.7

for 4th year =  \frac{75}{100} *1054.7 = $791.01

for 5th year =  \frac{75}{100} *791.01 = $593.25

Or we can use the following formula to find its resale value after 5 years:

2500*(0.75)^5 = $593.26
