Answer:

4. 73

5. 40°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. The sum of angles in a linear pair is 180°.

4. 45° +62° + k° = 180°

... 107 +k = 180 . . . . . collect terms, divide by °

... k = 180 -107 = 73 . . . . . subtract 107

_____

5. ∠STR = ∠SRT = 20°

... ∠STR +∠STU = 180°

... 20° + 4x = 180°

... 4x = 160° . . . . . . . . subtract 20°

... x = 40° . . . . . . . . . . divide by the coefficient of x

Nick went canoeing on the river he traveled 1 mile in 17 minutes.at this rate,how far will he travel in an hour and 25 minutes​
dem82 [27]

9514 1404 393

Answer:

  5 miles

Step-by-step explanation:

An hour and 25 minutes is 85 minutes. Using the given information we can find the distance d with the proportion ...

  \dfrac{\text{distance}}{\text{time}}=\dfrac{d}{85\text{ min}}=\dfrac{1\text{ mi}}{17\text{ min}}\\\\d=\dfrac{85\text{ min}}{17\text{ min}}(1\text{ mi)}\qquad\text{multiply by $85$ min}\\\\d=5(1\text{ mi})\qquad\text{simplify}\\\\d=\boxed{5\text{ mi}}

In 1 hour and 25 minutes, Nick will travel 5 miles.
