Find the morning side. round your answer to the nearest tenth. I would like to see the work please​

Step-by-step explanation:

Remark

x is opposite the 90 degree angle. It is the hypotenuse. 15 is opposite the 66 degree angle. It is the side opposite.The side opposite and the hypotenuse define the sin(theta).

Formula

sin(theta) = side opposite / hypotenuse

Givens

Theta = 66 degrees

Hypotenuse = x

Side Opposite = 15

Solution

Sin(theta) = 15 / x         Multiply both sides by xx*sin(theta) = 15           Divide by Sin(theta)x = 15/sin(theta)x = 15 / sin(66)sin(66) = 0.9135x = 15/ 0.9135x = 16.42

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
