Most fool-proof way to do this in my opinion is to simply expand everything and write it out, i.e.

Throwing this into a calculator, we get
23.032To the nearest cent, this gives us

If the value of x is 10. Then the measure of angle ∠COB will be 56°.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Given that A, O, and B lie on a straight line segment.
Then they make a linear angle that is 180 degrees.
Then we have
∠AOC + ∠COD + ∠DOB = 180
(3x + 94) + (x + 30) + (2x - 4) = 180
6x + 120 = 180
6x = 60
x = 10
Then the measure of angle ∠COB will be
∠COB = ∠COD + ∠DOB
∠COB = (x + 30) + (2x - 4)
∠COB = (10 + 30) + (20 - 4)
∠COB = 40 + 16
∠COB = 56°

Answer:
The table is attached!
Step-by-step explanation:
- 6 students play both musical instrument and a sport
- 3 students play neither a musical instrument nor a sport
- 14 students in total play a sport
Given: There are 24 students in the class
The number of students that does not play a sport is 24 - 14 = 10
The number of students that does not play a musical instrument but play a sport = 14 - 6 = 8
The frequency table thus is attached below:
