Answer:
B. 82.8°
Step-by-step explanation:
-Given that [tex]\theta=tan^{-1} 7.9321[/tex]
-We simply use our calculators to calculate the tan inverse 7.9321 as:
[tex]tan^{-1} 7.9321=82.81463[/tex]
-When rounding off to the nearest tenth, we check the digit in the hundredth:
- if more than 4, we round up
- if less than 5, we round down to the previous term
[tex]82.81463\approx 82.8[/tex]
Hence, the angle theta is 82.8°
