If the measure of AngleB is 40°, what measures can AngleA and AngleC be? Select all that apply. 20° and 30°
30° and 110°
55° and 85°
60° and 90°
70° and 70°

30° and 110°

55° and 85°

70° and 70°

Step-by-step explanation:

Given that:

To find the possible values for the other two angles .

Property of a triangle is that the sum of all three angles is always equal to .

OR

So, the sum of should be . We can select our answers according to this condition.

Option 1: 20° and 30°: the sum is hence, not correct.

Option 2: 30° and 110°: the sum is hence, correct.

Option 3: 55° and 85°: the sum is hence, correct.

Option 4: 60° and 90°: the sum is hence, not correct.

Option 5: 70° and 70°: the sum is hence, correct.

Hence, the possible answers can be:

30° and 110°

55° and 85°

70° and 70°
