For the right triangle shown, use the trig functions to find the value of x. Round your answer to the nearest tenth. 1. 9.1
2. 8.2
3. 9.4
4. 7

Step-by-step explanation:

First, recall the three basic right triangle trigonometry ratios.

Theta (θ) represents the angle. The angle (other than the right angle) is 70 degrees.

We are also given 2 sides: 10 and x.

Since we have the opposite and hypotenuse, we must use sine.

The angle is 70 degrees, the opposite is x, and the hypotenuse is 10.

We are solving for x. We must isolate x on one side of the equation.

Currently, x is being divided by 10. To "undo" the division, we must perform the inverse operation, which is multiplication. Multiply both sides of the equation by 10.

Round to the nearest tenth. The 9 in the hundredth place tells us to round the 3 up to a 4.

x is about 9.4

it would be 6xy and -16xy.
