Answer 1

Can you solve for \(x\)?

Answer 2

Would it be 25? @wio

Answer 3

@HeyImKae Tell me how you did it, and I'll tell you if it is corect.

Answer 4

I entered 70 * tan20 into my calculator! @wio

Answer 5

The angle and side are mixed up...

Answer 6

so would it be 20 * tan70? Because then I get 54

Answer 7

@wio

Answer 8

that sounds about right.

Answer 9

54 ft tree.

Answer 10

so

tan70 = x/20

than

x = 20 *tan70 = ?
