Answer:0.8 I think
Step-by-step explanation:
Since the angle altogether is 180°
You just need to subtract 28 and 48 from 180
28+48=76
180-76=104
Answer: 104°
Hope this helps!! <3
Step-by-step explanation:
(25x+8)°+(9x+2)°=180--->(1)(sum of angles on a straight line
(7y+5)°=(9x+2)°------------->(2)(vertical angles)
25x°+8°+9x°+2°=180°
34x°=170°
x=5°
from equation (2) substitute for x=5°
7y°+5°=9x°+2°
7y°+5°=9(5)°+2°
7y°=47°-5°
7y°=42°
y=6°
(x, y)=(5°,6°)
4x - 3y = 17
y = 3x - 4
(-1, -7)
