Step-by-step explanation:
9514 1404 393
Answer:
3.0
Step-by-step explanation:
The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values
x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3
x ≈ 3.0
Angle Z = Angle Q
Angle P = Angle Y
NQ = XZ
YZ = PQ
Angle X = Angle N
PN = YX
14. R= 60°
16. Equilateral and acute
