Answer:

36 ft.

Step-by-step explanation:

The given perimeter of triangle EDF is 12, in which the hypotenuse is 5. This means that it is a 3-4-5 triangle, meaning that ED = 3, DF = 4, EF = 5.

It is given that BC (the other triangle's hypotenuse) is 15. This means that the left triangle is to the scale factor of 3 of triangle EDF. Therefore, multiply 3 to all sides measurements, and then add all the sides to get the perimeter.

Hypotenuse: 5 x 3 = 15

Leg 1: 4 x 3 = 12

Leg 2: 3 x 3 = 9

Perimeter: 15 + 12 + 9 = 36

36 ft. is your answer.

Rampur Sarpanch requested one of his villager to donate a 6m wide land adjusted to his 132.8m long side of his right triangular

Furkat [3]

Answer:

The answer is 3030.72 m³

Step-by-step explanation:

Please refer to attached file for graphical representation.

Formulas used:

Area = (a*b)/2

Trigonometry: Tan (t) = opposite/adjacent

Assume:

Villager plot has 3 sides: hypotenuse=C, adjacent=A, opposite=B

Plot given has 3 sides: hypotenuse=z, adjacent=y, opposite=x

Angle common between them is t.

Step 1:

For t:

Tan (t) = a/b

Tan (t) = 123/50

Tan (t) = 2.46

Step 2:

For y:

Tan (t) = y/x

2.46 = y/6

y = 2.46*6

y = 14.76

Step 3:

Villagers old plot area: B = (a*b)/2 = (123*50)/2

B = 3075 m³

Step 4:

Plot donated area: C = (x*y)/2 = (6*14.76)/2

C = 44.28 m³

Step 5:

Villager remaining plot:

A = B-C

A= 3075-44.28

A = 3030.72 m³

Georgie joins a gym. She pays $25 to sign up and then $15 each month. Graph it. Label the y-intercept,the slope, and your axes.

Firlakuza [10]

The first thing you should do for this case is to find the equation of the line that best suits the problem and then plot it.
Let
x: number of months
y: amount paid.
The equation of the line is
y = 15x + 25
y-intercept = 25
the slope = 15
answer
Georgie pays (y axis) $ 15 dollars (the spole) monthly (x-axis) in the gym with a $ 25 registration (y-intercept)

Sketch the graph of each function

jenyasd209 [6]

Answer:

See diagram

Step-by-step explanation:

First, consider the graph of the parent function $y=\cos x.$ This function has the period $2\pi.$

Rewrite the function $y=2(1+\cos (x-\frac{\pi}{2}))$ as $y=2+2\cos (x-\frac{\pi}{2}).$ The graph of this function has the same period of $2\pi,$ is twice streched and translated $\frac{\pi}{2}$ units to the right and 2 units up graph of the parent function (see diagram).
