4.7(-5.2)= - 24.44
______________
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°)
The value of x would be 2
