Answer: The measure of the vertex angle = 80°
Step-by-step explanation:
Angle sum property of triangle : The sum of the measures of the angles for any triangle is 180 degrees.
So,
'
Then, vertex angle = 
Hence, The measure of the vertex angle = 80°
Y+4=10(x+3)
Y+4=10x+30
Y=10x+26
Answer:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
Step-by-step explanation:
Answer:
(1.5,1)
Step-by-step explanation:
The midpoint of G and H is at (2,2).
The midpoint if J and K is (1,0)
The midpoint of the two midpoints is (1.5,1)
You could also i.e. directly ask for the midpoint of H an K, OR, G and J, and you would get the same final result.
