Answer:
c=19.21
<C=90
<B=38.66°
<A=51.34
Step-by-step explanation:
12²+15²=c²
144+225=c²
c=19.21
<C=90
For angle B, the sinB=Opposite over Hypotenuse
sinB=12/19.21
sinB=0.62467
B=sin^-1(0.62467)
<B=38.66°
To find A, 180-90-38.66
<A=51.34

<u>Answer:</u>
Seiji’s earning = $250;
Gavin’s earning = $275
<u>Explanation:</u>
Consider Seiji’s earning to be $x
According to question, Gavin earned $25 more than Seiji
Then, Gavin’s earning = x + $25
According to question, total earning is $525
Then, x + x + 25 = 525
Solving for x,
2x + 25 = 525
2x = 500
x = 250
Therefore, Seiji’s earning, x = $ 250
Gavin’s earning = 250+25 = $275
The sum of the two acute angles is 90 degrees. Set this up in the form of the following equation.
We know this because the two angles are x and 3x + 12.
From here you just need to solve.
, or 19.5
This is the measure of one angle. The measure of the other angle is therefore, after a few calculations, 70.5.
19.5 degrees, 70.5 degrees.
