Answer:
The value of x is 20.
Step-by-step explanation:
Given that
Number of songs Marcus has = 10x+8
Number of songs Lara has = 15x-92
It is also given that they have the same number of songs that means both the expressions should be equal.
Putting both equal
This is a linear equation in one variable which can be solved using properties of equality
Subtracting 10 from both sides
Adding 92 on both sides
Dividing both sides by 5
Hence,
The value of x is 20.

Step-by-step explanation:
The area of sector of a circle (in radians) is:
Where
r is the radius
is the angle of the sector
We know the angle but we need the radius.
We are given the total circle's area is , putting in area of circle formula, we find the radius:
Now, using the values, we find the area of the sector:
Area of sector is
