Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°
What is the Tangent Ratio?
The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.
Thus:
- ∅ = ∠XYZ
- Opposite side = 13 cm
- Adjacent side = 4 cm
Thus:
tan (m∠XYZ) = 13/4
m∠XYZ = tan^-1(13/4)
m∠XYZ = 72.9°
