Answer 1

x = 75⁰

y = 40⁰

z = 140⁰

Step-by-step explanation:

For finding x ;

105⁰ + x = 180⁰ [AB is a straight line]

x = 180⁰ -105⁰

x = 75⁰

For finding y ;

x + 65⁰ + y = 180⁰ [Angle sum

property of ∆]

75⁰ + 65⁰ + y = 180⁰

y = 180⁰ -140⁰

y = 40⁰

For finding z ;

y + z = 180⁰ [BC is a

straight line]

40⁰ + z = 180⁰

z = 180⁰ -40⁰

z = 140⁰
