im ok, i can help
Step-by-step explanation:
The arcsine,

, is the inverse of the

function. This means that it takes as <em>inputs </em>what would usually be <em>outputs </em>for the

function and produces as <em>outputs </em>what would usually be <em>inputs </em>for the

function.
This can be particularly useful when you're trying to find an angle on a right triangle, but you've only been given the lengths of the sides. To find any angle

in a right triangle, just take

, where o is the side opposite

and h is the hypotenuse of the right triangle.
Answer:
10
Step-by-step explanation:
give brainliest please!
hope this helps :)
so these two angles add up to 180 degrees
7x -3 + 12x -7 = 180
7x+12x=180+7+3
19x=190
x=10
to check if this is true we can input 10 for x in each side.
7(10)-3 = 67
12(10)-7 = 113
113+67 = 180
