Answer:
x=-1
Step-by-step explanation:
x+3≠0
x≠-3
x²+5x+6=x+3
x²+5x+6-x-3=0
x²+4x+3=0
x²+x+3x+3=0
x(x+1)+3(x+1)=0
(x+1)(x+3)=0
x+3≠ 0
so x+1=0
x=-1
Answer:
Step-by-step explanation:
y-5=3(x+2)
y-5=3x+6
y-5-6=3x+6-6
y-1=3x
The positions of the sun, earth and shooting star form a right angled triangle, where distance between earth and sun is 'y', and the angle 'x°' is given
Now, in a right angled triangle using trigonometry, we can determine a side of the triangle is one of the sides and one of the angles is known
Here, if we use cos x =
we can determine the distance between the shooting star and the sun. This can be done because we know that the base is 'y', the angle is x° and the hypotenuse represents the distance between the sun and the shooting star
Note: cos values for each x are definite.
