To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
What was it less than, any absolute value is like a whole number, so yeah
The answer is CB, AC, and AB
40°
Step-by-step explanation:
∠ACB = ∠DCE ( vertically opposite angle )
Now...
a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )
a + 140° = 180°
a = 180° - 140°
a = 40°
hence the value of a is 40°
