A. Find the length of the midsegment of an equilateral triangle with side lengths of 12.5 cm.

pantera1 [17]

Answer:

a. 6.25
b. AT = 33
c. y = 3

Step-by-step explanation:

a. Midsegment is half the length of the parallel side:

12.5/2 = 6.25

b. Segment addition postulate:

AB = AT + TB = 3x + 6 + 42 - x = 2x + 48

Perpendicular bisector of segment divides the segment in two equal halves:

AT = TB
3x + 6 = 42 - x
4x = 36
x = 9

AT is:

AT = 3*9 + 6
= 33

c) The point on the angle bisector H is equidistant from the point E and G:

EH = HG
5y + 10 = 28 - y
5y + y = 28 - 10
6y = 18
y = 3

A carousel has 30 cars. Determine the angle of rotation that maps #6 to car #19.

ivolga24 [154]

Answer: The answer is 260°.

Step-by-step explanation: Given that a Carousel has 30 cars. We need to find the angle of rotation which maps car no. 6 to car no. 19.

Now, the Carousel will make a regular polygon with 30 sides and each car as a vertex.

So, angle of symmetry for the polygon is

$\theta=\dfrac{360^\circ}{30}=20^\circ.$

Number of sides from car 6 to car 19 = 19 - 6 = 13.

Therefore, the angle of rotation that maps car 6 to car 19 is given by

$\alpha=13\times \theta=13\times 20^\circ=260^\circ.$

Thus, the required angle of rotation is 260^\circ.
