Answer:
![65.4](https://tex.z-dn.net/?f=65.4)
Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
Therefore, we have:
![\cos 61^{\circ}=\frac{y}{135},\\t=135\cos 61^{\circ}=65.4492987333\approx \boxed{65.4}](https://tex.z-dn.net/?f=%5Ccos%2061%5E%7B%5Ccirc%7D%3D%5Cfrac%7By%7D%7B135%7D%2C%5C%5Ct%3D135%5Ccos%2061%5E%7B%5Ccirc%7D%3D65.4492987333%5Capprox%20%5Cboxed%7B65.4%7D)
Answer:
Step-by-step explanation:
Step 1: Solve one of the equations for one of the variables.
Step 2: Substitute that equation into the other equation, and solve for x.
Step 3: Substitute x values into one of the original equations, and solve for y.
"You" ran faster. 3 1/2 mi. turn into 3 5/10 mile. 1 2/5 mi. turn into 1 4/10 mile. 3/4 of an hour is 45 min. 1/3 of an hour is 20 min. Therefore you multiply 1 4/10 times 2 to get 2 8/10 mi. in 40 min. Since your friend needs 5 more min. to be at the same time as you, you divide 20 (1/3 of an hour) by 4. Which gives you 5 minutes. Now, take the 1 2/5 of the mile. and divide that by 4. Which according to Symbolab.com gives you 1/10. Now go back to the beginning, you ran 3 5/10 mi. in 45 minutes. Your friend ran 2 8/10 in 40 min. Now that we know 5 min. equals 1/10 miles, you can add that to your friend. which means she/he ran 2 9/10 mi. in 45 min. In conclusion, you ran farther that your friend in 45 min. "You" ran faster. (:
