Answer:
No
Step-by-step explanation:
Proportional is when there is a pattern in a graph/table
Answer: Center: (4,0), Radius: 4.
The measures of the angles are 30, 60 and 90 degrees.
Explanation:
I assume the question should read "the measures of the ANGLES of the triangle are in the ratio 2:4:6.
If the angles are in the proportion 2:4:6, the measures of the angles have the same scale factor
x
. And, the sum of the measures of the angles of a triangle is
180
.

The n-th term is given by
Then we can find the common ratio from the given terms.
The appropriate choice is -1.
