For this case what you should do is use the following trigonometric relationship:
sine (theta) = C.O / h
Where,
theta: angle
C.O: opposite leg
h: hypotenuse
Substituting values we have:
sine (80) = 9 / x

Answer:
Not equivalent
Step-by-step explanation:
if we simplify our two equations we get 6x + 2y and 4x + 4y. Which is not equivalent to each other
Answer:
About $4
Step-by-step explanation:
You have about 16, divide it by 4 and that’s your answer
The angles are in the ratio of 5:6:9.
Let the angles be represented by:
5x, 6x, and 9x.
The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9
The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.
