Question

Help me solve this, it’s trig

Answer 1

The answer is 6.451 or 6.5 rounded

Explanation:

The way to solve this is to find all the degrees inside the triangle first

you have two given degrees which are 21 and 90 degrees

add those numbers up and subtract it from 180. That is the last corner degree

you then use that information to find all the side lengths using the given hypotenuse length.

Btw its geometry not really trig.

Answer 2

Answer: 6.45 units

Explanation:

To solve for x, we will set up an equation using the trigonometric functions. We are given an angle (21 degrees), the opposite side of that angle (x), and the hypotenuse (18). For this, we will use the sine function.

sin(21) =
`(opposite)/(hypotenuse )`

sin(21) =
`(x)/(18)`

18sin(21) = x

x = 18sin(21)

x = 6.4506230 ≈ 6.45 units
