Answer:
DE = 39.64840676
CE = 35.3269891
Step-by-step explanation:
SOH CAH TOA
Thus,
sin(27) = 18/DE
tan(27) = 18/CE
DE = 39.64840676
CE = 35.3269891
the given expression is :
2(4√16x) - 2(4√2y) + 34√81x - 4(4√32y)
⇒ 8(√16x) - 8(√2y) + 34√81x - 16√32y
⇒8×4√x - 8√2y + 34×9√x - 16√16×2y [∵ √16 = 4 and √81 = 9]
⇒32√x - 8√2y + 306√x - 16×4√2y
⇒(32√x + 306√x) - 8√2y - 16×4√2y
⇒338√x -72√2y
