These angles are supplementary.
Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees. 82 degrees + 98 degrees = 180 degrees.
The answer would be 89.90558242
If u round it off, the answer will be 90
X^2 - 8x = (x - 4)^2 - 16
we add 16 to give x^2 - 8x + 16 which is a perfect square
x^2 - 8x + 16 = (x - 4)^2
answer is 16

Answer:
The circumference is 31.43 cm
The ratio of the circumference to the diameter is equal to 3:1
Step-by-step explanation:
Thed formular for the circumference of a circle is 2
r or
d
where d = diameter and r = radius
if d = 10 cm, and
= 3.143, then circumference of the circle can be given as
3.143*10 = 31.43 cm
The ratio of the circumference to the diameter can be given as 31.43:10
and that can be given as 3.143:1
or 3:1, for the nearest whole number
