Answer 1

`\displaystyle \angle2 = {49}^( \circ)`

Explanation:

remember that,

if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior angles

thus our equation is

`\displaystyle \angle2 + {86}^( \circ) = {135}^( \circ)`

cancel out 86° from both sides:

`\displaystyle \angle2 = {49}^( \circ)`

hence,

the measure of the missing angle is 49°

Answer 2

Solution given'

<2+45+86=180°[sum of interior angle of a triangle]

<2=180-131

<2=49°
