Question

Use ΔDEF, shown below, to answer the question that follows:

What is the value of x rounded to the nearest hundredth?

Answer 1

I'm assuming you are in geometry.

Let's use some Trig to solve this problem.

Sine, Cosine, and Tangent.

Chief S o/h C a/h T o/a. That's how I remember.

You are trying to find the opposite, and you have the adjacent. So, we would use Tangent to find our answer.

Tan 49= x/55 Multiply 55 on both sides.

55 (Tan 49)=x

I got 63.27026....

The hundredth place is the zero.

63.270= x

I hope this helps!

Plug that into a calculator.
