In ΔKLM, l = 26 cm, k = 56 cm and ∠K=22°. Find all possible values of ∠L, to the nearest degree.

An expert shot bits the target 95% of the time. What are the probabilities that he will miss the target: at least one time durin

Mkey [24]

If he hits the target 95% of the time, then you could say that he has a probability of 0.95, or 95% of hitting the target. Let p = the probability of hitting the target or p = 0.95. So you are interested that he misses the target at least once - this could be thought of as not getting a perfect score. So to get a perfect score, it is 0.95 for each target -- 0.95^15 for 15 targets is 0.464. Thus to miss at least one target he needs to NOT have a perfect score -- 1 - 0.464 = 0.536, or 53.6% of happening. Enjoy

Given: The coordinates of rhombus WXYZ are W(0, 4b), X(2a, 0), YO, -4b), and Z(-2a, 0).

Shkiper50 [21]

Answer:

∴ MNOP is Rectangle

midpoint of XY (N) : (a , - 2b)

Step-by-step explanation:

W (0 , 4b) X ( 2a , 0) Y (0 , -4b) Z (-2a , 0)

M (midpoint of WX) : ( (0 + 2a)/2 , (4b + 0)/2) i. e. (a , 2b)

N (midpoint of XY) : ( (2a + 0)/2 , (0 - 4b)/2) i. e. (a , - 2b)

O (midpoint of YZ) : ( (0 - 2a)/2 , (- 4b + 0)/2) i. e. (- a , - 2b)

P (midpoint of ZW) : ( (0 - 2a)/2 , (4b + 0)/2) i. e. (- a , 2b)

MN: length = 2b + 2b = 4b MN segment perpendicular to x axis (slope undefined)

NO: length = a + a = 2a NO segment parallel to x axis (slope = 0)

OP: length = 2b + 2b = 4b OP segment perpendicular to x axis (slope undefined)

PM: length = a + a = 2a NO segment parallel to x axis (slope = 0)

MN = OP and MN // OP and MN ⊥ PM

NO = PM and NO // PM and NO ⊥ OP

∴ MNOP is Rectangle

midpoint of XY (N) : (a , - 2b)

How can you find the area of a polygon that is not for which you know an area formula

kipiarov [429]

Answer:

See below.

Step-by-step explanation:

If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.

If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:

Example:

Find the area of the composite figure by splitting the figure into two shapes - two rectangles.

One rectangle is 2 x 9 = 18.

The other rectangle is 2 x 4 = 8.

Together the area is 18 + 8 = 26.

Pleaseeeee helpppppppppppppppppppppppp

natta225 [31]

I think it’s 309 cm because each side is 1 cm, there’s 3 sides, and 103 triangles. so 103x3=309 sides which means 309 cm

Please answer correctlyyyyyyy

spin [16.1K]

Answer: Choice C

x intercept is (4,0)

y intercept is (0,2)

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

Work Shown:

To find the x intercept, we plug in y = 0 and solve for x

2x+4y = 8

2x+4(0) = 8

2x+0 = 8

2x = 8

x = 8/2

x = 4

We have x = 4 pair up with y = 0. So we have (x,y) = (4,0) as the x intercept.

This is the location where the graph crosses the x axis.

--------------

The y intercept is a similar story, but we use x = 0 to find y.

2x+4y = 8

2(0)+4y = 8

0+4y = 8

4y = 8

y = 8/4

y = 2

The value x = 0 leads to y = 2. This gets us (x,y) = (0,2) as the y intercept.

This is the location where the graph crosses the y axis.
