Answer: x=3
Explanation: just did it :) plz name me brainliest :)))
Answer:
x = 6.928
Step-by-step explanation:
Since we don't know the hypotenuse, we will use tan
tanΘ = opposite/adjacent (Θ = theta, which is basically the variable for an angle)
tan30° = x/12
to find x, multiply 12 to the other side
12tan30° = x (plug this into a calculator)
x = 6.928
Add the lengths of all sides
