<h3>1)x=180°−(50°+60°) x = 180 ° - ( 50 ° + 60 ° ) =180°−110°=70°</h3>
<h3>2)x=180°−(30°+90°) Since it is a right angle so the third angle is a right angle. ...</h3>
<h3>3)x=180°−(30°+110°) x = 180 ° - ( 30 ° + 110 ° ) =180°−140°=40°.</h3>
<h3>4)Here; 50°+2x=180° Or, 2x=180°−50°=130° ...</h3>
<h3>5)This is an equilateral triangle. ...</h3>
<h3>6)This is a right angled triangle.</h3>
