The system has two solutions.
You can tell because the second equation is a quadratic and the first is a line, so the line passes through the quadratic twice.
Your answer is -4 !!
step 1.) write the number in exponential form with the base of
step 2.) reduce the index of the radical and exponent with
step 3.) with all that being said your answer would be -4 :D

Answer:
Option A
Step-by-step explanation:
It's given that cosθ =
Since, cosθ = =
=
By applying Pythagoras theorem in the right triangle,
(Hypotenuse)² = (Opposite side)² + (Adjacent side)²
(√5)² = (Opposite side)² + (2)²
5 = (Opposite side)² + 4
Opposite side = √(5 - 4)
= 1
Since, sinθ =
=
Since, sine is positive in IInd quadrant,
sinθ =
Therefore, option A will be the answer.
