Answer:
61.4°
Step-by-step explanation
Given
Length of the ramp = 23ft = hypotenuse
Base of the ramp = 11ft = Adjacent
Required
Angle of elevation x
Using the SOH CAH TOA identity
Cos theta =adj/hyp
Cos x = 11/23
Cos x = 0.4782
x = arccos0.4782
x = 61.42°
Hence the angle of elevation is 61.4°
Answer:
1220.4
Step-by-step explanation:
S.I.=P×R×T÷100
=6000×4.52×4 1/2÷100
=6000×4.52×9÷2×100
=60×4.52×9÷2
=30×4.52×9
=1220.4
