Answer 1

Answer:

this is the correct answer for this question

Answer 2

$\huge\sf{\underline{\underline{\red{Solution}}}}$

$\sf{Let \: that \: angle \: be \: x}$

$\sf{Supplement \: of \: 140 = 180- 140 = 40}$

So by the condition given in your question we get equation..

$\implies\sf{80percent × x = 40}$

$\implies\sf{80/100 \times x = 40}$

$\implies\sf{x = 40 x 100/80}$

$\implies\sf{x =\fbox\purple{ 50}}$

So the angle is of measure 50.
