Angle R and Angle T are complementary. If m of Angle R = 3x and m of Angle T = 2x, what is the value of x?
2 answers:
Complementary angle add up to 90. So, we can represent this relationship as an equation. 3x+2x=90. 5x=90. x=18.
3x + 2x = 90 (because <R and <T are complentary)
5x = 90
x = 18 Answer

Given the function:
f(x) = x³ + 3x² - 4x + 5
The graph of the function is (taken f:
According to the graph above, the maximum and minimum are 18.13 and 3.87, respectively
6 + 4 + 4 = 14 cm
2 * pi * r =
2 * 3.14 * 3 = 18.84 / 2 = 9.42
14 + 9.42 = 23.42
