Find the area of the kite.

a.18 square units
b.40 square units
c.27 square units
d.36 square units

The correct option is d.

Step-by-step explanation:

Area of a triangle is

The given kite has two congruent triangles with base 9 and height 4.

The area of kite is twice of the area of triangle with base 9 and height 4.

The area of kite is 36 square units.

Therefore the correct option is d.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
