Option C:

The value of m is 4.

Solution:

Given data:

AB = 4m – 15

BC = 5m –6

AC = 15

<u>To find the value of m:</u>

Using segment addition postulate,

AB + BC = AC

4m – 15 + 5m –6 = 15

Arrange the like terms together.

4m + 5m – 15 – 6 = 15

9m – 21 = 15

Add 21 on both sides of the equation,

9m = 36

Divide by 9 on both sides of the equation.

m = 4

The value of m is 4.

Option C is the correct answer.

Two cyclists start at the same point and travel in opposite directions. One cyclist travels 6 / km h faster than the other. If t
Alex17521 [72]
We can find the rate of each cyclist (assuming the rate is the amount they can travel in an hour)  by dividing by 4 and then adding 6.

216/4 = 54

54 + 6 = 60.

The rate of each cyclist is 54 km/h and 60 k/ph.

The measure of angle D in the inscribed triangle is as follows;

∠D = 63 degrees

<h3>How to solve circle theorem?</h3>

The circle theorem can be use to find the ∠D as follows;

The triangle BCD is inscribed in the circle.

Using circle theorem,

The angle of each triangle is double the angle of the arc it create.

Therefore,

arc BC = m∠D

m∠B = 134 / 2 = 67 degrees.

Therefore, using sum of angles in a triangle.

67 + 50 + m∠D = 180

m∠D = 180 - 50 - 67

m∠D = 63 degrees.
