The first would be 80 and the second is 8
Answer:
D. M<ABC = M<B'C'A'
Step-by-step explanation:
I took the test and got it right
Average speed for car a = 1280 / 16 = 80 mph
Car b travels at 80 - 0.5 = 79.5 mph.
Distance car b will travel in same time = 16*79.5 = 1272 miles.
Answer:
Step-by-step explanation:
47
15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.
16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.
17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.
18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.
19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.
20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.
Hope this helps! :)
