Find the perimeter of a rectangle whose length is 150 m and the diagonal is 170 m

460 m

Step-by-step explanation:

Use right triangle PSR with right angle S to find the length of PS.

The Pythagorean theorem can be used for this.

a^2 + b^2 = c^2

(PS)^2 + (SR)^2 = (PR)^2

(PS)^2 + (150 m)^2 = (170 m)^2

(PS)^2 = 22500 m^2 = 28900 m^2

(PS)^2 = 6400 m^2

PS = 80 m

PS = 80 m; SR = 150 m

perimeter = 2(length + width)

perimeter = 2(150 m + 80 m)

perimeter = 2(230 m)

perimeter = 460 m

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
