Answer:

\boxed{u = 6.0}

Step-by-step explanation:

Using the cosine rule

c^2= a^2+b^2-2abCosC

Here c = u , a = 11 , b = 12 and C = 30

u^2 = 11^2+12^2-2(11)(12)\ Cos 30\\u^2 = 121+144-2(132)(0.866)\\u^2 = 265-228.6\\u^2 = 36.37

Taking sqrt on both sides

u = 6.0   (To nearest tenth)

If the area of a triangular kite is 6 square feet and its base is 4 feet, find the height
KonstantinChe [14]
The height of the kite is 3 feet. Here’s
why;
We know that BH=2A (base times height is equal to 2 times the area) of any given triangle.
Lets plug in values;
BH=2A
4(H)=2(6)
Then simplify;
4(H)=12
Flip the equation to find the missing value;
12 divided by 4 is 3.
Check your work;
4(3)=6(2):
12=12
The height of the kite is 3 feet.
