Answer:
me, what's the question so I can see how to figure out the answer
Answer:
False
Step-by-step explanation:The circumference of a circle is approximately three times its diameter. If you divide the circumference by its diameter, the constant ratio is called Pi, which is an irrational number shown with this symbol: For example, the circle below has a radius of 4.5 inches.
Let y=kx
9=2k
k=4.5
when x=3
y=kx becomes
y=4.5 x 3
=13.5
Step-by-step explanation:
angles in a triangle add up to 180degree
- 3x + 36 + 90 = 180
- 3x =180 - 30 - 90
- 3x = 60
- divide through by 3 gives
- x = 20degree
- Therefore x =20°
