Answer:
56
Step-by-step explanation:
The median is the middle number of a sorted set from least to greatest. After sorting the set 61, 48, 52, 65, 56, 77, 54 the set is 48, 52, 54, 56, 61, 65, 77.
The middle number in this set is 56 so the median is 56
Answer:
CBD= 30
ABC= 90-30 = 60
x + 5 = 60
x= 55
Step-by-step explanation:
Answer:
you first find the radius which is given by r=√(5^2)+(-5^2)=5√2,and then you find the angle which is given by tan^-1(y÷x),that is tan^-1(-5÷5)=-45°.This angle lies between (5,-5)
so 360-45=315°.
The ordered pair will be (5√2,315°)
To obtain the second ordered pair 315°-180°=135°
(5√2,135°)
the two pairs of polar coordinates are (5√2,135°,
5√2,315°)
