Answer:
450cm²
Step-by-step explanation:
The area of the kite is made up of two pairs of congruent triangles. Find the area of these and add to get the kite's area. (area of triangle = (1/2)(base)height))
2(0.5*15*20)+2(0.5*15*10)
300+150
450

Given:


To find:
The quadrant of the terminal side of  and find the value of
 and find the value of  .
.
Solution:
We know that,
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II: Only sin and cosec are positive.
In Quadrant III: Only tan and cot are positive.
In Quadrant IV: Only cos and sec are positive.
It is given that,


Here cos is positive and sine is negative. So,  must be lies in Quadrant IV.
 must be lies in Quadrant IV.
We know that,



It is only negative because  lies in Quadrant IV. So,
 lies in Quadrant IV. So,

After substituting  , we get
, we get





Therefore, the correct option is B.
