Answer:
x = 59°
Step-by-step explanation:
See the attached diagram.
The first side of the triangle Δ ABC, i.e. AB of length 3, falls from right, then the second side BC of length 5, roses from left to right and the third side CA rises slightly from left to right.
The angle between AB and BC is 90° and that between AB and AC is x.
So, Δ ABC is a right triangle and hence,
[tex]\tan x = \frac{BC}{AB} = \frac{5}{3}[/tex]
⇒ [tex]x = \tan^{- 1} (\frac{5}{3} ) = 59^{\circ}[/tex] (Approximate) (Answer)
