You only need to know one side, you can use , tan, sin, or cos of the angles to find the other 2 sides.

Answer:
The height of the kite from the ground is 13.617 feet
Step-by-step explanation:
Given as :
The measure of the string = 30 feet
The angle of elevation from the boy to his kite = 27°
Let the height of the kite from ground = H feet
So, From Triangle
Sin angle = 
Or, Sin 27° = 
or, H = 30 × Sin 27°
I.e H = 30 × 0.4539
∴ H = 13.617 feet
Hence the height of the kite from the ground is 13.617 feet Answer
Answer:
<h3><em>3k^3+19k^2-33k+56</em></h3>
Step-by-step explanation:
3k^3-5k^2+7k+24k^2-40k+56
3k^3+19k^2-33k+56
Im going to assume you know the formula.
sooo.
x= -11 +- √ (11)² -4 (1) (-15)
---------------------------------
2(1)
= -11 +- √121- (-60)
-------------------------
2
= -11 +- √181
-----------------
2
= -11 +- 13.45
-----------------
2
Either: Or:
X = -11 - 13.45
x = -11 + 13.45 ---------------
2
----- ----------
2
x = 1.23 x= -12.23
