50 million, 5 million, 500 thousand
Answer:
27°
Step-by-step explanation:
Since BD is a diameter then arc BD = 180°
∠ APE = 180° - (90 + 63)° = 180° - 153° = 27°
The measure of the arc AE is equal to the angle at the centre subtended by it.
arc AE = ∠ APE = 27°
We first determine the height that the top of the ladder will reach given that the angle to be made is no greater than 75°. In the right triangle formed, the hypotenuse is 12. The trigonometric function that is derived from the scenario is,
x = (sin 75°)(12 ft) = 11.59 ft
Thus, the highest point that the ladder will reach should only be approximately equal to 11.59 ft.
20 cubes are in the model
