Question

Can someone help me please

Answer 1

131°

Explanation:

take the line with angle 49°

st line angle is 180°

49+90+a = 180 where (a+90=y)

139+a = 180

a = 180-139=. 41°

by opposite angles equal axiom a =x = 41°

y = 131°

Answer 2

x=41 et y=131

Explanation:

49+x=90

x=90-49=41

---------------------------

y=90+x

y=90+41=131
