Answer:

solution,

x+85+24=180 (being sum of angle of triangle)

x+109=180

Answer just below :-

Step-by-step explanation:

Let the third angle be x

Then;

24°+85°+x = 180 ( sum of interior angles of a triangle is 180°)

or; 109°+x = 180°

or; x = 180°-109°

:x=71°

Therefore the measure of third angle is 71°
