7x +2y =-17 ..... Finally, answer
2x + 3y = -5
+
5x -y = -12
---------------------------
7x +2y = -17
Answer:
y = 95° and x = 21°
Step-by-step explanation:
y + 85° = 180° { being co-interior angles }
y = 180° - 85°
y = 95°
y = 4x + 11°[ being vertically opposite angles ]
95° = 4x + 11°
4x = 95° - 11°
4x = 84°
x = 84° / 4
x = 21°

hope these helps you
Step-by-step explanation:
1. (2,3)&(0,7)
7-3/0-2
4/-2
=-2
2. (0,2)&(5,1)
1-2/5-0
=-1/5
3. (0,0)&(8,1)
1-0/8-0
=1/8
4.(0,2)&(6,4)
4-2/6-0
2/6
= 1/3
5.(0,1)&(4,2)
2-1/4-0
=1/4
6. (-1,6)&(4,2)
2-6/4-(-1)
=-4/5
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! :)
