The sum of complementary angles is 90 degrees, thus
3x + 6 + 3x + 18 = 90
=> 6x + 24 = 90
=> 6x = 90 - 24 = 66
=> x = 66 / 6 = 11
=> m<A = 3(11) + 6 = 33 + 6 = 39 degrees.
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
Answer:
10v+-15y+5
Step-by-step explanation:
