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