Hey Can I Get Some Math Help?
Hi, I need help with these three math problems. I appreciate the help! Here they are: the angle of depression, as measured from the top of a 41 foot tower to a reference point on the ground is 65 degrees. How far away, to the nearest foot, the reference point of the base of the tower? Jamison is a 20 foot board and props him with a block one foot on the far end to a daredevil jump ramp to make room for his bicycle. What is the measure of the angle of elevation the driveway to the nearest degree? A plane flies at an altitude of 7000 meters is 5 miles from the runway where the pilot plans to land. To the nearest degree, it should plane which corner of the depression to take? (Use 5280 meters = 1 mile) Thanks again! Cries, Timberwolf Can not I'm homeschooled through an online college.
Trig is difficult without photos. But just remember SOH CAH TOA you. A) The tower is the other side of the right triangle with right angle at the base of the tower, the distance from the tower the reference point is the adjacent side. So we use interface. Tan (41 '/ x) = 65 ° 41' / x = tan ^ -1 (65 degrees) x = 41 '/ tan ^ -1 (65 degrees) = 48 331 'B) The Board is the hypotenuse and the block is the other side of a right triangle with right angle on the block. So we use sine. Sin (1 / 20) Angle = angle degrees C = 2.864) Height is the other side, 5 miles is the adjacent side of a triangle with right angle directly below the aircraft on the ground. We use tangent. Also, 5 miles, 5 * 5280 = 26,400 meters tan (7000 '/ 26,400') angle = angle = 15.558 degrees
