Answer:

  • 5/3 m

Step-by-step explanation:

<u>Given triangle with: </u>

  • Height =  1/2 m and
  • Area = 5/12 m²
  • Base = ?

<u>Use the area formula and find b:</u>

  • A = 1/2bh ⇒
  • b = 2A/h

<u>Substitute values:</u>

  • b = 2*5/12 ÷ 1/2
  • b = 5/6 * 2
  • b = 5/3 m

Answer:

{9, 7, 5, 3, 1}

Step-by-step explanation:

All you do is plus in each domain value in for the x and you get the range every time.

-2(-2)+5

-2(-1)+5

-2(0)+5

-2(1)+5

Kim is watching a space shuttle launch from an observation spot 2 miles away. Find the angle of elevation from Kim to the space
hammer [34]

Answer:

<h2><em>46.4°</em></h2>

Step-by-step explanation:

Find the diagrammatic representation in the attachment given.

We can see that the diagram is a right angled triangle. To get the angle of elevation, we will use one of the trigonometry identity SOH, CAH, TOA.

Given the adjacent of the triangle to be 2miles (observation spot from the point of launch)and the opposite (side facing the elevation angle) as 2.1miles (the height), we will use TOA.

tan∅ = opposite/adjacent

tan∅ = 2.1/2

tan∅  = 1.05

∅ = tan⁻¹1.05

∅ = 46.4°

<em>Hence the angle of elevation from Kim to the space shuttle, which is at a height of 2.1 miles is approximately 46.4°</em>

Help! WHAT IS THE VALUE OF X, and can you show how you got it please?
miss Akunina [59]
See the picture attached with letters to better understand the problem

in the right triangle ABD
applying the Pythagoras theorem
8²=AD²+(x+4)²-----> AD²=64-(x+4)²------> equation 1

in the right triangle ADC
applying the Pythagoras theorem
12²=AD²+(2x+1)²-----> AD²=144-(2x+1)²------> equation 2

equate equation 1 and equation 2
64-(x+4)²=144-(2x+1)²-------> 64-[x²+8x+16]=144-[4x²+4x+1]
64-x²-8x-16=144-4x²-4x-1
4x²-x²-8x+4x=144-1-64+16
3x²-4x=95
3x²-4x-95=0

using a graph tool----> to resolve the second order equation
see the attached figure N 2
the solution is
x=6.33

the answer is
x=6.33 units
