X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
Answer:
sinx = p/h , cosx = b/h , tanx = p/b
you can use these relations
Step-by-step explanation:
p = perpendicular = side opposite to the angle
h = hypotenuse = side opposite to the right angle
b= base
if no angles are given, p and b can be interchanged
