Step-by-step explanation:
Explanation: To find an angle of a triangle we add the angles we know about
EXAMPLE: 50 + 120. We need to find the third angle.
We know that Angles of triangles should add up to 360
So to find the third angle we add the angle we know about.
EXAMPLE: 50 + 120 = 170 then we Subtract the sum of a triangle *360*
EXAMPLE: 50 + 120 = 170
EXAMPLE: 170 - 360
EXAMPLE: = 190
That's how we find a third angle!
If this doesn't clarify how do to it enough just let me know and i can try to explain more in detail!
Hope this helps you!!!
Have a nice day!
