Question

B Find the sum.pls solve properly​

Answer 1

Answer:

x=90

y=120

z=150

x+y+z=90+120+150

x+y+z= 360

Step-by-step explanation:

angle y + 60=180

angle y=180-60

angle y=120

angle x+ 90=180

angle x=180-90

angle x=90

in traingle

ANGLE 1 +ANGLE 2+ANGLE 3=180

ANGLE1+90+60=180

ANGLE 1=180-90-60

ANGLE 1=30

angle z+30=180

angle z=180-30

angle z=150
