Remember SOHCAHTOA which means, the Sin of an angle is equal to the Opposite side divided by the Hypotenuse, the Cos of an angle is equal to the Adjacent side divided by the hypotenuse, and the Tangent of an angle is equal to the Opposite side divided by the Adjacent side. So as long as you have two sides of a right triangle, then you can find the angles and the length of the third side.

To find the cosine of an angle in a right triangle divide the adjacent by the?
hypotenuse.
What is the adjacent angle to an acute triangle whose hypotenuse is 135 degrees?
The answer should be 67. 5 degrees. The adjacent angle equals the hypotenuse divided by two. After calculation the answer should be approximately 68 degrees.
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
What is cos of angle a with a hypotenuse of 13 and adjacent of 5 and a opposite of 12?
Cos(angle) = adjacent / hypotenuse. Cos(a) = a/h Substitute Cos(X) = 5/13 = 0.384615... A = Cos^*-1( 0.384615 .... A = 67.38013505... degrees.
Is this statement true or false The sine of an angle in a right triangle is the ratio of the length of the side adjacent to that angle to the length of the hypotenuse.?
False because sine ratio = opposite/hypotenuse
