Answer:
A = (a+b)/2
G = sqrt(ab)
Step-by-step explanation:
To find the arithmetic mean, we add the numbers together, then divide by how many numbers
A = (a+b)/2
To find the geometric mean, we multiply the numbers and take the nth root
G = (ab) ^ 1/2
G = sqrt(ab)
Answer:
Angle 1: 141 degrees
Angle 2: 39 degrees
Angle 3: 141 degrees
Step-by-step explanation:
Angle 2 and Angle 4 are equal since they are vertical angles. This means that Angle 2 is equal to 39 degrees.
Angle 1 and Angle 4 add up to 180 degrees. We call these supplementary angles. This means that Angle 1 is equal to 180-39=141 degrees.
Angle 1 and Angle 3 are vertical angles, so Angle 3 is also equal to 141 degrees.
2
+ -
3
the opposite of - is a + number therefore - is +
This is what it would look like
