From the figure and statement provided, select the proper TO PROVE statement.

If two angles of a triangle are equal, the sides opposite those angles are equal.
MN = AB
AB + BC = AC
m is parallel to l
AB = BC
a is parallel to b

2 5/8 is the final answer! : )

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)

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
