Answer:

  x = 4

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the remote interior angles.

  18x +5 = (46) +(-1 +8x)

  10x = 40 . . . . . . . . . . . . . subtract (5+8x) from both sides, simplify

  x = 4 . . . . . . divide by 10

__

<em>Additional comment</em>

The exterior angle is (18)(4) +5 = 77°. The marked unknown interior angle is -1+(8)(4) = 31°. The sum of the two remote interior angles is 46°+31° = 77°. The unmarked interior angle is 180°-77° = 103°.

A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use
agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T =  minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

                  Find the circumference of the circle and show work. [refer to  

                  attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

          Formula for Circumference of a Circle:-

        \dashrightarrow\star\bigstar\boxed{\boxed{C=2\pi r}}}

Where

  • C = circumference
  • π = pi (3.14…)
  • r = radius, which in this case is equal to 8

Substitute the value of r and solve:-

         C=2π(8)

        On simplification,

     

C=16π

On further simplification,

C=50.3

Therefore, we conclude that the circumference of this circle is

\dashrightarrow\star\bigstar\boxed{\boxed{\underline{\bold{C=50.3\:yd}}}}\bigstar\star\dashleftarrow

<h3>Good luck.</h3>

Julie has a large red apple in her hand that is 4 ft off the ground. A blue bird sees the apple at an
Dafna1 [17]

Answer:

Step-by-step explanation:

so from the silly drawing,  you can see that the triangle is 4 feet off the ground, and that we want to find the Opp side from our angle of 15 °

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

use TOA to find the Opp side of the triangle .. which is labeled X

Tan(15) = X / 15

15* Tan(15) = X

4.019   =   X

so the bird is up 4 feet in the tree.. not very high up, plus the 4 feet that the apple is already off the ground, soo

the tree... to where the bird is, at least, is 8.019 feet..

did this make sense?  :/  

hope the drawing helped  :P
