Question

Can someone please explain to me how I do this?

Answer 1

Answer:

x = 12.77 cm

Step-by-step explanation:

In this problem, we will use trigonometry to find the missing value. I will use the 70 degree angle to find it.

12cm is the opposite value for 70, and x is the hypotenuse. We will use Sine to solve this problem.

Since we are missing the hypotenuse, we set up the equation like this -

x = 12/Sin(70)

This leads us to our answer, x=12.77 cm (rounded)
