Angles A and B are complementary. If cos A = 7x − 9 and sin B = 4x + 15, what is the value of x?
Karo-lina-s [1.5K]

The value of x according to the described angles is; 8

<h3>Complementary angles</h3>

If two angles A and B are complementary, it follows that A + B = 90 and Cos A = Sin B.

From the statement above, it follows that;

  • 4x + 15 = 7x -9

Collect like terms;

  • 15 +9 = 7x - 4x

  • 3x = 24

Divide both sides by 3;

x = 24/3 = 8.

How do you reduce 75/100?
Anestetic [448]
Find the greatest common factor and then divide each number by it. 

in this case the gcf for 75 and 100 is 25.

75 divided by 25 = 3
100 divided by 25 = 4

so 75/100 simplified = 3/4
