Clint's salary increased from ​$24000 to $36000 over a​ three-year period.​ Helen's salary increased from ​$29000 to $43, 500 ov
lesya [120]

<u>Answer:</u>

Helen's salary increased more.

<u>Step-by-step explanation:</u>

We know that Clint's salary increased from ​$24000 to $36000 over a​ three-year period.​

So the increase in Clint's salary will be = 36000 - 24000 = $12000

While Helen's salary increased from ​$29000 to $43, 500 over the same period of 3 years.

So the increase in Helen's salary will be = 43500 - 29000 = $14500

Therefore, in absolute terms, Helen's salary has increased more.

Answer:

Answer is 71.95°

Step-by-step explanation:

Cosine formula is

a^2=b^2+c^2-2bc(cosA)

cos A =b^2+c^2-a^2/2bc

if a= 119,b=94,c=173

cos A=94^2+173^2-119^2/2(94*173)

=8836+29,929-14,161/2(16,262)

=38765-14,161/32,524

=24604/32,524

=0.7564

cos A=0.7564

cos^-1=40.85°.that's for angle A.

Using the same formula

B=31.1°

C=180-(40.85+31.1)

C=180-71.95

C=108.05

Since angle on a straight line is 180

therefore x is 71.95

Also the sum of angles A and B
