Step-by-step explanation:
The first step to finding the median is to sort the numbers from small to large.
3, 7, 17, 19, 20, 21, 31, 43, 46
then you find the middle number, equal numbers on other sides.
20 is in the middle because that leaves 4 on each side.
A = b x h x 1/2
a = 30 x 31.5 x 1/2
a = 15 x 31.5
a = 472.5
Answer:
The answer is -15

Answer:
x = 74°
Step-by-step explanation:
The angle whose vertex lies on the circle, that is angle x is one- half the measure of it's intercepted arc, that is
