<h3>Right angle triangle:</h3>
- A right angle triangle has one of its angle as 90 degrees. The sides can be found using trigonometric ratios.
Therefore,
sin 60° = opposite / hypotenuse
sin 60° = b / 500
cross multiply
b = 500 sin 60°
b = 500 × 0.86602540378
b = 433.0127
b = 433 meters

Y = (x - 1)² + 2
y = (x² - x - x + 1) + 2
y = (x² - 2x + 1) + 2
y = x² - 2x + (1 + 2)
y = x² - 2x + 3
x² - 2x + 3 = 0
x = <u>-(-2) +/- √((-2)² 4(1)(3))</u>

x = 1 + 2 x = 1 - 2
x = 3 x = -1
y = x² - 2x + 3
y = (3)² - 2(3) + 3
y = 9 - 6 + 3
y = 3 + 3
y = 6
(x, y) = (3, 6)
or
y = x² - 2x + 3
y = (-2)² - 2(-1) + 3
y = 4 + 2 + 3
y = 6 + 3
y = 9
(x, y) = (-1, 9)
Answer:
the answer is w=26cm
