Look at the triangle: a right angle triangle is shown with hypotenuse equal to 13 centimeters. an acute angle of the triangle is labeled as x degrees. the side adjacent to the acute angle has length 12 centimeters and the side opposite to the acute angle has length 5 centimeters. what is the value of sin x°? 12 ÷ 13 13 ÷ 5 13 ÷ 12 5 ÷ 13

For this case we have:

By definition, an acute angle is less than 90º.

In addition, having a rectangular triangle, the sine of an angle is given by the leg opposite that angle divided by the hypotenuse of the triangle. So:

Observing the triangle of the attached image we have:

So,

Option D

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
