Question

what is angle cba measure​

Answer 1

Answer:

We know that the sum of all three angles of a triangle is 180°. So adding up the given values and putting them equal to 180 to solve for x: Therefore, the measure of angle CBA will be = ° 101°

Answer 2

Answer:

option c

Step-by-step explanation:

consider triangle acd

angle adc = angle acd

so x = 20°

angle acd + angle acb = 180°(linear pair)

angle acb = 180-80 = 100°

consider ∆abc

angle bac + angle acb + angle cba = 180°

angle cba = 180-20-100 = 60°
