Question

Kindly ans part b. i and ii of given pic

Answer 1

b) i) x° + 10° = 70°

=> x = 60°

ii) (x+10)° = (2x-25)

=> x = 35°

So,

2y+x+10 = 3x+y-15

=> 2x-y = 25

=> y = 70-25

=> y = 45°

Hope it's helpful to you.

Answer 2

Step-by-step explanation:

ii- x+10= 2x-25

x-2x= -25-10

-x=-35

x= 35

so,2x-25=x+10

next,2y+x+10=3x+y-15

2y+35+10=105+y-15

2y-y= 105-15-35-10

y= 45

so,2y+x+10 = 3x+y-15
