Question

solve second que please.. if uh can on notebook nd snd attachment... ​

Answer 1

Answer:

a) we know that

x=60

so, 2x= 60 x 2= 120

2x +y =180

120 +y =180

y= 180 - 120

y= 60

b) we know that y=40

so, 2x +y= 180

2x + 40 = 180

2x= 180 - 40

2x = 140

x = 140/2

x= 70

Answer 2

Answer:

Step-by-step explanation:

a.when x=60°

then,a/q,

2x+y=180°[straight ∠]

2*60°+y=180°

120°+y=180°

y=60°

b.when y=40°

then,a/q,

2x+y=180°

2x+40°=180

2x=140°

x=70°

so the answers are 60°and 40° respectively....
