Answer:
you are correct :D
Step-by-step explanation:
The law used for determining the measure of unknown sides and angles of a triangle. The measure of the largest angle in triangle abc is 98.25 degrees
<h3>Law of cosines</h3>
The law used for determining the measure of unknown sides and angles of a triangle. It is expressed as:
c² = a² + b² - 2abcosC
Given the following
c = 16
a = 12
b = 9
Substitute
16² = 12² + 9² - 2(9)(12)cosC
256 = 144 + 81 - 216cosC
31 = -216cosC
cosC = -31/216
C = 98.25 degrees
Hence the measure of the largest angle in triangle abc is 98.25 degrees

Let the number be the variable x
4 times the number is 4x
the sum of 8 and 4 times a number is 28
4x+8=28
4x=28-8
4x=20
x=20/4
x=5
The answer is 36 people.
<span>30 people is five-sixths of the club: 30 people is 5/6.
The total number of people x is 100% = 1
30 : 5/6 = x : 1
x = 30 * 1 : 5/6
x = 30 : 5/6
x = 30 * 6/5
x = 36
