Answer:
55.6
Step-by-step explanation:
The mean is found by adding all the numbers together, and dividing by the amount of numbers there are. Note you must round to the tenths place.
(50 + 52 + 52 + 55 + 56 + 56 + 56 + 58 + 58 + 59 + 60)/11
First, combine and add all terms within the parenthesis, and then divide:
(612)/11 = 55.63... , or 55.6 (rounded to the nearest tenth place).
55.6 is your answer.

The bottom line is a straight line that is equal to 180 degrees.
The three angles above it all need to add together to equal 180.
One angle is given as 20, so the other two need to add together to equal 160 ( 180-20 = 160)
Those two angles form the angle ACE so the answer would be 160 degrees,
Answer 160 degrees.
Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)
