Answer:
2 days late
Step-by-step explanation:
He had saved 320 initially
Step-by-step explanation:
Let the amount he saved be 'a'
Amount spent = 20 + 40 + 30
= 90
His grand father gave 50
At the end he has 280
280 = a - 90 +50
a = 280 -50 +90
= 320
He had saved 320 initially
Answer:
Angle of elevation = 80°
Step-by-step explanation:
A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?
To solve for angle of elevation, we use the Trigonometric function of Tangent.
tan θ = Opposite side/Adjacent side
Opposite side = Height of the tower = 217 ft
Adjacent side = 38ft
tan θ = 217/38
tan θ = 5.6315789474
θ = arc tan 5.6315789474
= 79.930937301°
Approximately = 80°
