Answer 1

<LNK = 20°

Explanation:

`angles \: of \: triangle \: add \: upto \: {180}^(0) \\ in \: that \: scalene \: triangle \\ {25}^(0) + {135}^(0) + < lnk = {180}^(0) \\ < lnk = {180}^(0) - ( {135}^(0) + {25}^(0) ) \\ < lnk = {20}^(0)`

Answer 2

A)20°

Explanation:

As we know a triangle contains 180°

So according to the question

The equation is

25°+135°+x=180°

160°+x=180°

x=180°-160°

x=20°
