Answer:
Explanation:
According to the unit circle, 
and are the radian measures you are looking for because all <em>y-coordinates</em> are associated with the <em>sine</em> function, so when evaluating, you will arrive at this:
I am joyous to assist you at any time.
The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.

Answer:
No.
Step-by-step explanation:
If these sides come out true in the Pythagorean Theorem, then it is a right triangle.
a² + b² = c²
56² + 80² = 100²
3136 + 6400 = 10000
9536 ≠ 10000
Since these values do not come out true in the Pythagorean Theorem, it is not a right triangle.
