The cuic equation is -1 and 2i
Given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
It’s A! hope this helps you out!
Its the second one
Point slope formula is:
Y - (y1) = m ( x - (x1) )
M is the slope so -5/7
( 6 is (x1) , 2 is (y1) )
Y-2=-5/7(x-6)
Answer:
399.6 square miles
Step-by-step explanation:
The Area of a sector =
x/360° × πr²
r = 13.4 miles
x = 255°
Hence,
255°/360° × π × 13.4²
= 399.5739336 square miles
Approximately = 399.6 square miles
