A ladder is placed 30 inches from a wall. It touches the wall at a height of 50 inches from the ground. The angle made by the la
dder with the ground is
59.04 degrees, and the length of the ladder is __
inches.
1 answer:
Answer:
applying trigonometry
base= 30inches
height= 50inches
angle between ladder and ground = 59.04°
for the length of the ladder...
sin59.04 = opposite side ÷ hypotenuse
sin59. 04 = 50inches ÷ hypotenuse
0.8575 = 50 inches ÷ hypotenuse
cross multiply;
hypotenuse = 50inches ÷ 0.8575
the length of the ladder = 58.309inches
