Answer:
148.5 miles
Step-by-step explanation:
its 148.5 miles because you times the 16 1/2 to the 9 and get 148.5 miles
3. m=43
4: m=-46
5:m=-44
6:=-16
The answer is the first one
<span>Replace tan θ with sin θ/cos θ
= sin²θ/cos θ + cos θ
Now multiply the right-hand side by cos θ/cos θ to get the same denominator:
= sin²θ/cos θ + cos²θ/cos θ
= (sin²θ + cos²θ)/cos θ
The numerator is equivalent to 1:
= 1 / cos θ
= sec θ</span>
