<span>When the temperature of the air is 50°C, the velocity of a sound wave traveling through the air is approximately Answer</span>: 361 m/s
Answer:
n ≤ 6
Step-by-step explanation:
5 + 2n ≤ 17
2n ≤ 12
n ≤ 6
This is a right triangle
so
Cos x = 109 / 134 then x = cos⁻¹ (109/134) = 35.567°
sin y = 109 / 134 then y = sin⁻¹ (109/134) = 54.433°
and
the third side = √(134² - 109²) = 77.94
