Step-by-step explanation:
Sum of the interior angles of the triangle =180°
Let the third angle be x°
Therefore, x°+30°+100°=180°
x = 180°-130°= 50°
Answer:
50 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180 degrees
a+b+c=180
Substitute 30 in for a, and 100 in for b
30+100+c=180
Combine like terms
130+ c=180
Subtract 130 on both sides
c=50
So, the third angle is 50 degrees
Hope this helps! :)
