Question

Find the value of x and the value

A: x=20,y=45
B:x=45,y=20
C:x=60,y=120
D:x=90,y=60

Answer 1

we have that

[3y°+6y°+2x°+90°]=360°
9y°+2x°=270°

but we know that
2x°=90°------------------ > x=45°
therefore
9y°+2x°=270°--------> 9y°+2(45°)=270°
9y°=270°-90°------------------> y=20°

the answer is
x=45°
y=20°
the option B:x=45°,y=20°
