4. Two anglies of triangle are 45 and 55° Find the measure of third angle​

Answer 1

sum of angles of a triangle=180°

angle1+ angle2 +angle3= 180°

45°+55°+x=180°

x=180-55-45

x=80°

Q:-Two angles of triangle are 45 and 55° Find the measure of third angle

$\huge\tt\underline\blue{ANSWER }$

------>>>>Here is your answer<<<<--------

➜The sum of angles of all angles in a triangle is 180°.

∴45°+55°+third angle(say x) =180°

100°+x=180°

x=180°-100°

x=80°

∴The measure of third angle is 80°
