Answer:
C
Step-by-step explanation:
(22/8+3)+(15/8-3)=5, (55/8+3)+(40/8-3)=13
(22/11)+(15/5)=5, (55/11)+(40/5)=13
2+3=5, 5+8=13
It's basically either guess and check, or you can use system of equations (but that would take way more time)
All you can do to solve this is isolate the y
3x+2y=9 (subtract 3x from both sides)
2y=9-3x (divide both sides by 2)
y=9/2-3/2x or y=-3/2x+9/2
Hope this helps
Answer:
(D)
<u>Use the law of sines:</u>
- 13 / sin x = 12 / sin 67°
- sin x = 13 sin 67° / 12
- sin x = 0.997
- x = arcsin (0.997)
- x = 85.6°
(E)
<u>Find the third angle:</u>
<u>Use the las of sines:</u>
- x / sin 61° = 21 / sin 71°
- x = 21 sin 61° / sin 71°
- x = 19.4 cm
