<u>Answer:</u>
angle a =
<u>Step-by-step explanation:</u>
The angles in a triangle add up to 180°.
∴ ∠a + 13° + 13° = 180°
⇒ ∠a + 26° = 180°
⇒ ∠a = 180° - 26°
⇒ ∠a = 154°
Answer:
He will have paddled the canoe for 4 km.
a. The distance paddled out is equal to the distance paddled returning.
Step-by-step explanation:
Let <em>d </em>be the distance that Roger Waters paddled out.
Let <em>t </em>be the time for the travel he paddled out and <em>t' </em>be the time for returning.
Then from the formula ,
<em>t </em>= and <em>t' </em>=
Total time for the journey = 1 hour 30 minutes = 1.5 hours
So, <em>t</em> + <em>t'</em> = 1.5
3<em>d</em> = 6
<em>d</em> = 2 km
The total distance he will have paddled the canoe = 2<em>d</em> = 2(2) = 4 km.
Clearly, the distance he paddled out = the distance he returned.
Hence, the correct option is A.
