Question

Plz help on these two.

Answer 1

5)x= 67° and y= 32°

(x-15)°=52°(vertically opposite angles)

=>x= 52+15° = 67°

Similarly, 4y= 128°(vertically opposite angles)

=>y=128/4= 32°

6) x= 5° , y= 22°

12x+15=75°(vertically opposite angles)

12x=75-15°

12x=60°

x= 5°

6y-27°=105°

6y= 105+27°

6y= 132°

y= 22°
