Answer:
Step-by-step explanation:
Formula
c^2 = a^2 + b^2
Givens
Hypotenuse (c) = 45
a = 40
b = ?
Solution
45^2 = 40^2 + b^2
2025 = 1600 + b^2 Subtract 1600 from both sides.
2025-1600 = 1600-1600 + b^2 Combine
425 = b^2 Take the square root of both sides.
√425 = √b^2
b = 20.62
Answer
The third side is 20.62 cm
With 180° < <em>θ</em> < 270°, we know that both cos(<em>θ</em>) < 0 and sin(<em>θ</em>) < 0.
Then from the Pythagorean identity, it follows that
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1 ==> sin(<em>θ</em>) = -√(1 - cos²(<em>θ</em>))
and so
sin(<em>θ</em>) = -√(1 - (-8/13)²) = -√105/13
Recall the double angle identity for sine:
sin(2<em>θ</em>) = 2 sin(<em>θ</em>) cos(<em>θ</em>) = 2 (-√105/13) (-8/13) = 16√105/169
