Pretend y is the angle of depression.
Tan y= opposite/ adjacent
Tan y = 16.2/ 48.3
Y= tan-1( 16.2/ 48.3)
Angle = 18.5416
Your answer would be -16.
Answer:
Pythagoras theorem states that c²=a²+b²
14²=12²+x²
14²-12²=x²
196-144=x²
52=x²
√52=√x²
7.2111025509279785=x
rounded up to the nearest hundredth=7.21
