The answer would be C.
(7sqrt3)^2 + (7sqrt3)^2 = c^2
49*3 = 147
147+147= c^2
294 = c^2
sqrt 294 = c
17.1 = c
8) The angles of an octagon are 135 degrees and since they're divided in the middle the angle measures are 67.5.
So 180-67.5-67.5=45 so the measure of the inner degree of each small triangle is 45. There are 3 triangles between points T and P (going clockwise) so its 45(3) is 135 degrees. Your answer is 135 degrees
9) There are 5 triangles between U and I (going counterclockwise) so its 45(5) which is 225
Answer:
= (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
= (n + 1)²
