The cosine of an angle in an isosceles right triangle is always √(2) / 2.
Answer:
11.19
Step-by-step explanation:
$17,160
286,000·0.06=17,160
31.6
80 * .55 = 48.4 (Current amount of water)
80 - 48.4 = 31.6 (Needed amount of water)
x = 13.75
(4x + 5) - 10 = 50
4x + 5 - 10 = 50
4x - 5 = 50
4x = 50 + 5
4x = 55
x = 55/4
