Question

Please help!
If angle 1 = 60^o and angle 2 = 90^o, what is the measurement of angle 3?

Answer 1

I am assuming this is a triangle. If so, all angles in a triangle add to 180^o. To find the third angle,

180-60-90=30

Therefore, assuming this is a triangle, the third angle is 30^o.

Answer 2

Answer:

30

Step-by-step explanation:

If this is a triangle, the angles need to equal 180. 60 plus 90 is 150. 180 minus 150 equals 30.
