Find the perimeter of the following shape: shape abcd is shown. point a is at 7, 5. point b is at 6, 3. point c is at 3, 2. point d is at 4, 4. 10.8 11 11.4 11.6

A. 10.8.

Step-by-step explanation:

We are given that  a shape ABCD . The point A is (7,5), B (6,3), C(3,2) and D (4,4).

By using distance formula we find sides of given shape and then find perimeter.

Distance formula:The distance between two points and

=

Length of side AB=

Length of side AB=units

Length of BC=

Length of side BC= units

Length of side CD=

Length of side CD=

Length of side AD=

Length of side AD=

Therefore, the perimeter of given shape ABCD=AB+BC+CD+AD

The perimeter of given shape ABCD=

The perimeter of given shape ABCD=.

Substitute

The perimeter of given shape=4.46+6.32

The perimeter of given shape=10.78=10.8(round off)

Hence, the perimeter of given shape=10.8 units

Therefore, option A is correct.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
