The answer is D. Multiply the number of times Tristan swam around the lake by the distance to get the total distance that Tristan swam. If he swam 1/4 a mile 8 times, then he swam 2 miles. Since it takes Tristan an hour to finish one mile and he swam 2 miles, you need to multiple 60 minutes by 2 to get the time Tristan took to swim. I hope that this was helpful and if so please leave a good rating and thanks and maybe even Brainliest answer. Thank you and have a good day!
Step-by-step explanation:
<A + < B = 90° { being complementary angles)
2x + 10° + 3x + 15° = 90°
5x = 90° - 15° - 10°
5x = 65°
x = 13°
Now
<B = 3x + 15° = 3 *13° + 15° = 54°
Hope it will help :)
Difference first do the work in the parenthesis and then subtract. Hoped it helped :3
