The value of x is 7 for the given collinear points a, b, and c as b is the mid-point of ac.

According to the given question.

a, b, and c are collinear points. Which means all points a, b, and c lie in a same plane.

b is lies between a and c.

Also,

ab = x, bc = x and ac = 24.

Since, b lies in between a and c, and it is given that ab = x and bc = x.

Which means b is the mid point of ac.

Therefore,

ab + bc = ac

Substitute the values of ab, bc and ac in the above equation.

⇒ x + x = 14

⇒ 2x = 14

⇒ c = 14/2

⇒ c = 7

Therefore, the value of x is 7.

Find X to solve to problem and find all the angles
sesenic [268]

Answer:

Step-by-step explanation:

x + x + 65 °+ 25° = 180° ( being sum of angles of triangle )

2x + 90° = 180°

2x = 90°

x = 45

now

<A = 45°

< B = x + 65° = 45 °+ 65 °= 110°

< C = 25°

Hope it helps :)
