Answer is A
Answer:
yes it is less then a right angle
Step-by-step explanation:
Answer:
Mean- 70.8
Median- 70
Mode- 60
Step-by-step explanation:
Mean: 20+20+50+50+50+60+60+60+60+60+60+70+70+70+80+80+80+80+90+90+90+90+100+100+130= 1770
1770/ 25= 70.8
Median: cross off on each sides till you get to the middle number
Mode: 60 occurs the most frequent
1) "a" and 60° are vertical angles, hence equal. a = 60°
2) "b" is the supplement to 60°, so is 180° - 60° = 120°. b = 120°
3) "d" is the supplement to 65°, so is 180° - 65° = 115°. d = 115°
4) "e" and 65° are vertical angles, hence equal. e = 65°
5) "g" is the supplement to 55°, so is 180° - 55° = 125°. g = 125°
6) "h" and 55° are vertical angles, hence equal. h = 55°
Wouldn't it be -12? Because when you add or multiply negative and positive together it gives positive.
