Parallelogram WXYZ. <br><br> WX = 13x + 15<br> YZ = 19x - 9<br><br> Find the values of x and y.
sweet-ann [11.9K]

Answer:

Step-by-step

sum of the adjacent angles of parallelogram is supplementary.

Therefore,

Q + R = 180°

4y+7 + 10y-37 = 180°

14y - 30° = 180°

14y = 210°

y = 210°/14

y = 15°

Could not found X in the question.

HELP !!! | 20 Points.
RUDIKE [14]

Answer:

No. The ladder is too steep.

Step-by-step explanation:

Length of ladder = 17 feet.  This is the hypotenuse.

Side a of a right triangle = 16.6

To answer this, you need one of the trigonometric functions.  

Opposite = 16.5

hypotenuse = 17

The function you need is the sine function.

Sin(theta) = opposite / hypotenuse

sin(theta) = 16.5 / 17

Sin(theta) = 0.97059

theta = sin-1(0.07059)

theta = 76.07

No the ladder is too steep.

x-2 = 5 we separate parenthesis.

x(-2) = 5(+2)

x = 7

We can check this as what the x-2 is saying is  7-2 = 5

The Drawing of a building, shown below, has a scale of 1 inch to 30 feet.
dem82 [27]
The complete question in the attached figure

we know that
[scale]=1 in / 30 ft
scale=[measure in the drawing]/[measure in the actual]
[measure in the actual]=[measure in the drawing]/[scale]
so
[measure in the drawing]=1.25 in
scale=1/30

then
[measure in the actual]=[1.25]/[1/30]------> 1.25*30-----> 37.5 ft

the answer is
<span>the Actual height is 37.5 ft</span>
