6 0

Answer:

86.60 units²

Step-by-step explanation:

It’s composed of two equilateral triangles (60-60-60).

(10√3)/2=8.66 (the height of each triangle

area = 1/2bh

1/2(10)(8.66)=43.30127

43.30127x2=86.60254

We want to place a bench measuring 7.05 feet in the center of a platform that is 40.75 feet long
AnnyKZ [126]
40.75 - 7.05= 33.7
33.7 / 2 = 16.85 
16.85 ft. should be on each side of the 7.05 ft. bench

Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below: Two rectangular tiles, rect
guapka [62]
From the given figure,
the length of segment SP is 5 - 1 = 4,
the length of segment SR is 8 - 1 = 7,
the length of segment QR is 5 - 1 = 4,
the length of segment PQ is 8 - 1 = 7.

The length of segment MJ is 4 - 1 = 3,
the length of segment ML is 8 - 4 = 4
the length of segment KL is 4 - 1 = 3
the length of segment JK is 8 - 4 = 4

<span>segment SP to segment SR is 4 : 7
</span><span>segment MJ to segment ML is 3 : 4
</span>
<span>segment PQ to segment QR is 7 : 4
</span>segment JK to segment KL is 4 : 3

Because the ratio of any corresponding segments of the two rectangles to another segment is not equal, the two rectangles are not similar.

Therefore, the correct statement is "<span>The two tiles are not similar because segment PQ is to segment QR is 7:4 and segment JK is to segment KL is 4:3"</span>

FIND THE SLOPE OF THE LINE...<br><br> A) 1/2<br><br> B) 2<br><br> C) - 1/2<br><br> D) -2
Ainat [17]

Answer:

The slope would be C) -1/2

Step-by-step explanation:

To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)

m(slope) = (y2 - y1)/(x2 - x1)

m = (-3 - -4)/(0 - 2)

m = 1/-2

m = -1/2

The measure of angle θ is 7 pi/6 . The measure of its reference angle is... °?, and sin θ is ...?
hjlf

Alright, let get started.

We have given the angle Ф as 7π/6.

And we are asked to find its reference angle (in dgrees)

So, we will first change 7π/6 from radian to degrees by multiplying 180/π

Ф = 7π/6 * 180/π

Ф = 7 * 180/6 = 210 degrees

Now, reference angle is the angle between X axis and the terminal side of given angle.

Please refer to the diagram attached.

The terminal side of angle 210 is lying in 3rd quadrant.

The angle between X axis and its terminal side is 210 - 180 = 30 degrees

Hence refernce agle of 210 degree or 7π/6 is 30 degrees. : Answer

We are also asked to find sin Ф

We could find it by using unit circle. sin 210 = - 1/2 Answer

Hope it will help :)
