Question

Find a and b mathematics​

Answer 1

Answer:

a is 40 b is 40

Explanation:

a=b vertically opposite angles

a+140=180

180-140=a

40 =a

b=40

Answer 2

Answer:

$\red{ \bigstar}{ \frak{ \underline \purple{correct \: question}}}$

$\pink{ \bigstar}{ \frak{ \underline \orange{correct \: answer}}}$

=>\_Pus+\_Suo=180° [linear pair]

=>140°+A=180°

=>A=180°-140°

=>A=40°

$\red{ \bigstar} \huge \boxed{ \fcolorbox{white}{pink}{answer}}$

To A Is 40°

Now,\_A=\_B [Alternate angles are equal]

\_B=40°

So, \_A=40° [ Linear pair]

\_B=40°[Alternate angles are equal]
