- The Blue Angels, the Navy's elite flying squadron, have performed for more than 427 million fans since their inception in 1946.† Suppose the two Blue Angel jets at points P and A in the diagram have elevations of 1570 feet and 1000 feet, respectively. Both are flying east toward the viewing crowd at T. From T, the measure of the angle of elevation of jet P is 5°, and the measure of the angle of elevation of jet A is 2.2°. (Round your answers to two decimal places.) (a) How far from the crowd is each of the jets? Plane P ft Plane A ft (b) Find the distance d between the nose tip of jet A and the nose tip of jet P.d = ft(c) What is the ground distance from the nose tip of each jet from the crowd?

Two lines intersect each other in a circular plane with an equation x2 + y2 + 4x – 6y = 12. These lines exactly intersect at the center of the circle and forms a region which looks like a pie slice called a sector. Line 1 and 2 have y-intercepts of 9 and 4, respectively. Determine the area of the sector formed by the intersection of said lines. (Note: The area of the sector is calculated as AA = θθ360°ππrr2, where θ is the angle between the intersecting lines in degrees)arrow_forward
