Question

what is the value of x to the nearest tenth?

Answer 1

use the tangent ratio

Answer 2

how do I do it? (Im not smart lol) Please teach me

Answer 3

tangent (W) = Opposite / Adjacent

Answer 4

tangent (64) = x/4

Answer 5

that is also the way they are asking for an approximate value, because there isn't really an exact value for tangent 64.

Answer 6

k

Answer 7

(( possibly, polynomial approximation for tan(x) at x=64 , if you wanted to go without a calculator... don't worry about this specific post))

Answer 8

alrighty, anyway, we have got:
tan(64)=x/4

can you solve for x?

Answer 9

so how would i solve for x?

Answer 10

2.05/4????

Answer 11

calculate tan(64) using a calculator, and then multiply both sides times 4.

Answer 12

tan(64)=x/4
2.05=x/4

and now multiply both sides times 4

Answer 13

8.2

Answer 14

yes, \(x\approx 8.2\)

Answer 15

ok

Answer 16
