The said triangle that is asked is a right triangle which has a proportion on each angle of 3 and 6. These proportions are the angles, which is 45, 45, and 90, which also means that the two rays of the triangle are the same and proved that ab= ac that makes the angle a is a 90 degree in value.
The value of cosθ = 3/√34, cscθ = -√34/5, and tanθ = -5/3 if the (−5, 3) be a point on the terminal side of θ.
<h3>What is the Pythagoras theorem?</h3>
The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
We have (−5, 3) be a point on the terminal side of θ.
Perpendicular = -5
Base = 3
From Pythagoras' theorem:
Hypotenuse² = (3)² + (-5)²
Hypotenuse = √34
cosθ = 3/√34
cscθ = -√34/5
tanθ = -5/3
Thus, the value of cosθ = 3/√34, cscθ = -√34/5, and tanθ = -5/3 if the (−5, 3) be a point on the terminal side of θ.

you can check be substituting the a value into (x-3)(x+a) once you substitute you can use foil to check and see if things make sense
