Answer:
The best estimate for the number of hours the family drove is 28.8 Hours.
Step-by-step explanation:
The distance Jarrod's family drove is 1778 miles and their average speed was 61.7 miles/hour, and we need the best estimate for the number of hours the family drove. For this we use the distance formula
and use solve for t:
Thus the best estimate for the hours driven is 28.8 hours.
<em>It is only an estimate because the speed given is the average speed.</em>

Answer:
34 = 35
Step-by-step explanation:
34x35
By Cosine Rule:
CosT = (s² + r² - t²) /(2sr)
<span>CosT = (10² + 11² - 7²) /(2*11*10)
</span>
<span>CosT = 172 /220 </span>≈ 0.7818
T = Cos⁻¹(0.7818)
T ≈ 38.57°
T ≈ 38.6°
