An angle of elevation of 58 degrees with the ground means
that the angle started at the x-axis and terminates on the first quadrant
region through a counter clockwise direction. Imagining a triangle, the string
of the kite becomes the hypotenuse, the angle 58 degrees is the angle between
the hypotenuse and the ground, and the height of the kite is the side opposite
to the angle.
Therefore, we can calculate for the height of the kite
using the sin function:
sin θ = opposite side / hypotenuse
sin 58 = opposite side / 50 m
opposite side = 50 m * sin 58
opposite side = 42.4 m
<span>Therefore the kite is about 42.4 m above the ground.</span>

Answer:
x = - 1
Step-by-step explanation:
(8x + 12) = 3 ( multiply both sides by 4 to clear the fraction )
3(8x + 12) = 12 ( divide both sides by 3 )
8x + 12 = 4 ( subtract 12 from both sides )
8x = - 8 ( divide both sides by 8 )
x = - 1
Answer:
A Quadratic Equation can have upto 2 roots maximum. So,if one of the roots is a Real number, there are following two possibilities:
1) The other root is also a real number, but a different number
2) Its a repeated root, so the other root is the same number.
The other root cannot be a complex number as its not possible for one root to be real and other to be complex. Either no root will be complex or both will be complex roots.
Following are 3 possibilities for the roots of a quadratic equation:
- 2 Real and Distinct roots
- 2 Real and Equal roots
- 2 Complex roots
