Solve each literal equation for 'K'.<br> a) T=4K/M b) bm-Kn=14

77julia77 [94]

a) T = 4K / M

1) multiply both sides by M => TM = 4K

2) divide both sides by 4 => K = TM / 4

Answer: K = TM / 4

b) bm - Kn = 14

1) add Kn to both sides => bm = 14 + Kn

2) subtract 14 from both sides => bm - 14 = Kn

3) divide both terms by n => K = [bm - 14] / n

Answer: K = [bm - 14] / n

Use the law of cosines to solve for the measure of the largest angle in triangle abc.

MariettaO [177]

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
