Question

(trigonometry) solve for x

Answer 1

Answer:

x°=12.15°

Step-by-step explanation:

Sin(x°)=4/19

x°=Sin^-1(4/19)=12.15°

Answer 2

Answer:

12.15

Step-by-step explanation:

Using x as the reference, the 4 is in the opposite side from x and the 19, being opposite the right angle, is the hypotenuse.

sine = opposite/hypotenuse

sin x = 4/19

To isolate the x, do the inverse sine on each side.

${sin}^{ - 1} \sin(x) = {sin}^{ - 1} ( \frac{4}{19} )$

use the inverse sine function of your calculator (usually 2nd sine) to find the value of of the right-hand side.

x = 12.15
