Wait do you need help with this orrrrr
The triangles are always 180 degree so add the 2 and subtract it from 180<span />
Answer: ; indirect variation ; x = 2.4
<u>Step-by-step explanation:</u>
direct variation is when: ; where k is the constant rate
indirect variation is when: xy = k ; where k is the constant rate
In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation:
since k = 24, then input y = 10 and k = 24 into the equation above:
x = 2.4
Answer: C) 1963.5
Solve for area. Pi (π) is a non-algebraic number that represents the ratio of the distance around the circle (circumference) to its diameter, usually estimated as 3.14. To solve for area, square the radius (radius times radius) then multiply by 3.14.
