Answer:
x=50°
Explanation:
Since a right triangle equals a total area of 180° you have 40° given and since it is a right triangle you also have 90° given so all we have to do is add 40° + 90° = 130° subtract 130° - 180° which would give you 50°
x= 50 °
all angles of a triangles is equal to 180
x= 180° - (90° +40°)
x= 180° - 130°
x= 50°
