Question

please solve this please ​

Answer 1

Answer:

y=50° and x=60° because sum of interior angle of triangle is 180°

Answer 2

Answer:

i. x=60   y=50

ii x=45   y= 45  

iii x=40   y = 110  

Step-by-step explanation:

y=180 - 130= 50  (Sum of Linear angles=180)

x= 180-(70+50)= 60 (Sum of total angles of a triangle=180)

y=  180-(85+50)= 45 (Sum of total angles of a triangle=180)

<D=180-85=95 (Sum of Linear angles=180)

x=180-(95+40)=45 (Sum of total angles of a triangle=180)

y= 180-70= 110 (Sum of Linear angles=180)

x=180-(110+30)=40 (Sum of total angles of a triangle=180)
