Angle of elevation is 37°

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

As we have the opposite side 75 ft to the angle and the hypotenuse 125 ft, we can find the sine value as,

sin θ = opp/ hyp

       = 75/125

     = 0.6

θ = sin⁻¹ (0.6) = 36.9°≈ 37°

So angle of elevation is 37°.

The graph below shows the design for the front view of a doghouse that Jeremy plans to build. If each square on the graph repres
dexar [7]

Based on the graph, the total perimeter of the doghouse Jeremy plans to build s 28 feet (twenty-eight feet).

<h3>What is the perimeter?</h3>

This is the total distance of all the sides in a shape. Due to this, the general formula is:

  • Perimeter = side + side + side.

<h3>What is the perimeter of the doghouse?</h3>
  • Horizontal side: 8 feet
  • Vertical sides: 10 feet
  • Diagonal sides: 10 feet

8+10+10= 28 feet.

Note: This question is incomplete because the graph is missing; here is the graph:

At 3 P.M, ship A is 150 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 25 km/h. How fast is
klemol [59]
 <span>Starting position: 

Let B start at origin(O) & A is at (-150 ,0) ie 150 km west of the origin . At 3pm , t= 0 
A is changing its position at ( 150-35t) km/h 
& B is changing its position at 25t km/h 

Therefore 

AB^2 = OA^2 + OB^2 /// Pythagoras Theorem 
= (150-35t)^2 + ( 25t)^2 
= 22 500 - 10 500 t + 1225t^2 +625t^2 
= 22 500 - 10 500t + 1850t^2 
AB = ( 22 500 - 10 500t + 1850t^2)^1/2 

d (AB) /dt = 1/2 * ( 22 500 - 10 500t + 1850t^2)^-1/2 * ( - 10 500 + 3700t) 
= ( - 5250 + 1850t) / ( 22 500 - 10 500t + 1850t^2)^1/2 

At 3pm , t=0 
At 7pm , t= 4 

So d (AB) /dt = ( -5250 + 1850*4) / ( 22500 - 10500*4 + 1850*4^2)^1/2 
= 2150 / 100.5 
= 21.4 km/hr

</span>The distance between the ships changing at 7 P.M. is with a speed of 21.4 km/hr.
