Question

Can you please help me out ?

Answer 1

Lets get started :)

The formula is given
We know tan =
`(opposite)/(adjacent)`
opposite = 8.9 cm
adjacent = 7.7 cm
tan⁻¹ (
`(8.9)/(7.7)`) = x {Given}
x = 49.13467137
x ≈ 49° (to the whole degree)

Answer 2

We use the trigonometric definition:
Tanx = (a) / (b)
a: opposite leg.
b: adjacent leg.
Substituting we have:
Tanx = (8.9) / (7.7)
Clearing the value of x we have:
x = Atan ((8.9) / (7.7))
x = 49.13467137
whole degree
x = 49 degrees.
Answer:
x = 49 degrees.
