4x + 5x = 90 ... because complementary angles summed together equal 90 degrees
9x = 90
x = 10
smaller angle = 4x = 4(10) = 40
and if you wanted to find out the larger angle = 5x 5(10) = 50
and to check that they are complementary, 40 + 50 = 90
So first you add 83 to 245 because the submarine descends lower into the water than it was before. Then you subtract 103 because the submarine ascends 103 feet. So you get 208. The submarine is 208 feet below the sea level
