Answer 1

Answer:

the ____ answer ____ is _____40°

Step-by-step explanation:

the_sum_of_all_angles_of_triange_=_180°

80°+60°+a=180°

140°+a=180°

a=180°-140°

a=40°

Answer 2

Answer:

b. 40°

Step-by-step explanation:

The sum of three angles of a triangle is always 180°.

Therefore, A/Q, 80°+60°+a = 180°

= 140°+a =180°

= a = (180°-140°)

= a = 40°

Hence, the value of a in the given figure is 40°
