What is value of x?<br> Enter your answer in the box.
marin [14]

Answer:

x \ = \ 10

Step-by-step explanation:

Let point D be the point where the straight line drawn from point A meets the straight line BC, it is evident that \triangle ABD and \triangle ACD is similar given that both triangles share the same angle, \angle BAD \ = \ \angle DAC. Hence, the ratio of the sides of each triangle is the same. Specifically,

                                              \displaystyle{\frac{x+4}{8} \ = \ \frac{2x+1}{12}}.

Performing cross multiplication yields

                                           12\left(x+4\right) \ = \ 8\left(2x+1\right) \\ \\ \rule{0.15cm}{0cm}12x+48 \ = \ 16x+8 \\ \\ \rule{1.1cm}{0cm} 4x \ = \ 40 \\ \\ \rule{1.3cm}{0cm} x \ = \ 10.

What is the area of the kite?
enot [183]

The area of the kite is 2.25 square feet

<h3>How to determine the area of the kite?</h3>

The area of the kite is calculated using:

Area = 0.5 * pq

Where p and q are the diagonals of the kite.

In this figure,

p = 3

q = 0.75 * 2 = 1.5

So, we have:

Area = 0.5 * 3 * 1.5

Evaluate

Area = 2.25

Hence, the area of the kite is 2.25
