Answer:

x-y=4

Step-by-step explanation:

(y+4)/(1+4) = x/5

(y+4)/5 = x/5

y+4 = x

-x+y= -4

x-y = 4

Two sides of a triangle are equal in length and double the length of the shortest side . The perimeter of the triangle is 36 inc

Firdavs [7]

Answer:

The length of the sides of the triangle are as follow: Two sides are 14.4 inches long and the shortest is 7.2 inches.

Step-by-step explanation:

P = 36in // perimeter of triangle

P = A + B + C //equation for perimeter of a triangle

A = B or B = A //Showing that two sides are equal in length

A = 2C and B = 2C //Showing that the two equal sides are each doubled of the shortest side

C = A/2 and C = B/2 //Showing the same thing as the top, but in terms of the shortest side

Solve for C //First we solve for the shortest side as it's easiest

36 = A + B + C

36 = 2C + 2C + C //Use substitution for A and B

36 = 5C

C = 7.2in

Solve for A

A = 2C

A = 2(7.2) //Use what we solved for C

A = 14.4in

Solve for B

B = A

B = 14.4in //Same as A

Check Work

P = A + B + C

P = 14.4 + 14.4 + 7.2

P = 36

Please help me with 1,2,3 and show me how you get it the answers and how you get it do not send me link please I need help someo

Answer:

1) 20 cm

2) 22.4 in

3) 15 ft

Step-by-step explanation:

For this question, you have to use the Pythagorean theorem.

Why?

Well, because it is a right triangle and you have 2 sides given and you want to find the third side.

Now let's solve this problem!

For number 1 we have:

a = 16 cm and B = 12 cm

you need to find the 3rd side which is c (aka the hypothenuse)

so let's write the equation:

a^2 + b^2 = c^2

Then we substitute with what we have given.

16^2 + 12^2 = c^2

Using a calculator solve the equation

400 = c^2

Now we have to find the square root from both sides of the equation.

c = 20 cm (That's the final answer)

For number 2 we have:

a = 10 in and b = 20 in

we follow the same steps as in number 1

a^2 + b^2 = c^2

10^2 + 20^2 = c^2

500 = c^2

c = 22.4 in (That's the final answer)

For number 3 we have:

a = 9 ft and b = 12 ft

a^2 + b^2 = c^2

9^2 + 12^2 = c^2

225 = c^2

c = 15 ft (That's the final answer)
