Question

do the 10th sum both parts

Answer 1

in 1st
x=110 by angle sum property
y =70 by linear pair
z=110
exterior angle of triangle

Answer 2

Hello Mate

The answer for the first part is :

angle 45+ angle 25= angle 70

angle x = 180 - 70 (ASP)

angle x= 110

and angle y = 180- 110 (LP)

angle y = 70

second part:

ext. angle =75

angle y+ 30 = 75 (ext angle)

angle y = 75-30

angle y= 45

angle x= 180- 75 (ASP)

angle x= 105
