5. A man observes a balloon at a 62° angle of elevation. He knows the balloon is hovering directly above a point on the ground, 900 feet to the east, as shown in the figure below. sin 62° s 0.8829 cos 62° s 0.4695 tan 62° s 1.8807 6 ft 900 ft If the man is 6 feet tall, what is h, the altitude of the balloon, to the nearest whole foot? Use the trigonometric ratios provided and enter your answer in the box. feet
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
