C can be found using the tangent trigonometric function since the opposite side and adjacent side is given hence respectively using it in action would be;
C=7/3 which is also the same as 2.33…
and rounding that would give you the answer of 2.3
B) Only (1, 3)
2x + 3y = 10
Substitute (2,2) into the equation:
2(2) + 3(2) = 10
4 + 6 = 10 which is true
Substitute (1,3) into the equation:
2(1) + 3(3) = 10
2 + 9 is not equal to 10
Answer:
C
4296 - 80% = 859.2 + 4297 = 5155.2
Rounded up to the nearest answer
