What is the value of x and y​

Mathematics
1 answer:
swat323 years ago
4 0

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°)
