Answer 2

Question :-

two angles of a triangle are of measures 105° and 30° . find the measure of the third angle ?

Formula :-

sum of all angle of a triangle = 180°

To find :-

the measure of the third angle

Solution :-

$\dashrightarrow\sf \: let \: the \: third \: angle \: be \: x \: \\ \\ \dashrightarrow\sf \: 105° \: + 30° \: \: + \: x \: = 180° \: \\ \\ \: \dashrightarrow\sf \: 135° \: + x = 180° \: \\ \\ \dashrightarrow\sf \: x \: = 180° \: - 135° \: \\ \\ \dashrightarrow\sf \: x \: = 45° \: \\ \\ {\small{\bold{\underline{\therefore\: The\: third\: angle\: is\: \bold{\pink{45°}}\: .}}}}$
