Given: abc is a right triangle with right angle c. ac = 15 centimeters and m< a = 40°.what is bc, to the nearest tenth?

 or  

The hypotenuse is the longest side of the triangle.

The opposite side is the side across from a point/angle.

The adjacent side is the side next to the point/angle.

To find BC, you can do this:

tan 40° = O / A

tan 40° =   Multiply 15 on both sides

15(tan 40°) = BC

12.6 = BC

BC = 12.6 cm

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
