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

plz mention the units

The answer is 45 because 105 + 30 = 135 and 180 which is the sum of all triangles is subtracted i.e 180 - 135 = 45.

105+30+?=180           105+30= 135          135-180=50        the third side = 50

45 is the answer

It is 45 degrees.i got the answer by using angle sum property that is the Sam of all the three angles of a triangle is 180degreesso 105+30+x=180 135+x=180 X=180-135 =45

thanks
