Question

Tommy is drawing a triangle with angles measuring 41° and 123°, and the included side measures 6 cm.

What is the measure of the third angle of the triangle?
A) 16°
B) 57°
C) 139°
D) 196°

Answer 1

A) 16°
the workout
123°+41°+x°(the third angle) =180° (all the angle in a triangle sum up to 180°)
164°+x=180°
x=180°-164°
therefore, x=16°
