What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.

Answers

Answer:

That is a 30 60 90 triangle.

In such a triangle the "middle" size = short side * sq root (3)

height = 5 * sq root (3) =  8.6602540378

Area = (1/2) * 5 * 8.6602540378

Area = 2.5 * 8.6602540378

Area = 21.6506350946 square centimeters

            Put In Decimal Form:41.5692193817^3

Step-by-step explanation:

4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.

A=1/2(4)(4√3)

0.00285
2.85
0.285
ОО
0.0285

Answers

Answer:  Choice D)  0.0285

=========================================

Explanation:

You move the decimal point two spots to the left to go from 2.85% to 0.0285

Or you can think of it like this:

2.85% = (2.85)/100 = 0.0285

since "percent" means "per 100"

Step-by-step explanation:

all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.

Answer:

  15.08 m

Step-by-step explanation:

You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.

Angle XZW is 180° -108° = 72°

The circumference is C=πd, so the arc of interest is ...

  XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m

  XW ≈ 15.08 m

_____

If you use π = 3.14, then your answer will be 15.07 m.

What is rotation?

Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.

Given:

LMNP is rotated 90° clockwise around the origin.

If we rotate the figure in LMNP  about 90 degrees then the coordinates will change into

(x, y)  to (y, -x).

As, x= 3, y=4

Hence, the coordinates of M is M’(4,-3).

What would you multiply to make the y variable cross out?

-5x + y = -3

3x - 8y = 24

Answers

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3
