Question

Opposite = 1.5.

adjacent = 4.

find the acute angle​

Answer 1

20.56

Explanation:

tan∅=opposite/adjacent

=1.5÷4

=0.375

then to get ∅ find the tan inverse of 0.375 you'll get 20.55604...

put it in two decimal point...20.56°

Answer 2

Explanation:

tanθ = opp/adj

θ = arctan(1.5 / 4)

θ = 20.55604521958346...

θ = 20.6°
