Answer:

0.9

Step-by-step explanation:

Basic angle =

cos { }^{ - 1} ( \frac{4}{5} ) = 36.870 \: degrees \\

Therefore,

theta = 180 + 36.870 = 216.87 \: degrees

Therefore,

\sin( \frac{theta}{2} )  =  \sin(108.435 )  = 0.9

The dotted line represents the mid segment of the trapezoid. Find the value of X
Ganezh [65]

<u>Given</u>:

Given that the bases of the trapezoid are 21 and 27.

The midsegment of the trapezoid is 5x - 1.

We need to determine the value of x.

<u>Value of x:</u>

The value of x can be determined using the trapezoid midsegment theorem.

Applying the theorem, we have;

Midsegment = \frac{b_1+b_2}{2}

where b₁ and b₂ are the bases of the trapezoid.

Substituting Midsegment = 5x - 1, b₁ = 21 and b₂ = 27, we get;

5x-1=\frac{21+27}{2}

Multiplying both sides of the equation by 2, we have;

2(5x-1)=(21+27)

Simplifying, we have;

10x-2=48

Adding both sides of the equation by 2, we get;

10x=50

Dividing both sides of the equation by 10, we have;

x=5

Thus, the value of x is 5.

What is the midpoint of the segment shown below?
Elan Coil [88]

Answer:

(3, 2.5)

Step-by-step explanation:

2 points are given:

(-1,2)

and

(7,3)

The midpoint coordinate (x,y) is found by:

  • taking average of the x coordinates of the 2 point given, and
  • taking average of the y coordinates of the 2 points given

We sum and divide by 2, to get the average. So,

X coordinate of midpoint is:

(-1 + 7) /2 = 6/2 = 3

Y coordinate of midpoint is:

(2+3)/2 = 5/2 = 2.5

So,

Midpoint (3,2.5)
