Answer:
Step-by-step explanation:
Let the angle is x
Imagine the right triangle with the angle x, with side opposite to angle x 15 ft and the adjacent side is 50 ft.
<u>Use trigonometry:</u>
- tangent = opposite / adjacent
- tan x = 15/50
- tan x = 0.3
- x = arctan 0.3
- x = 16.7° (rounded)
Answer: Option 3
Step-by-step explanation:
Cross Multiply by 'x - 5'
Hence
y(x - 5) = 4 -3x
xy - 5y = 4 - 3x
Move all the terms containing an 'x' to one side of the equals and all the others to the opposite side.
xy + 3x = 4 + 5y
Factor out 'x'
x(y + 3) = 4 + 5y
'Cross' divide by 'y + 3'
x = ( 4 + 5y) / (y + 3 )
'x' is now the subject.
