Answer:
x= 50 °
Step-by-step explanation:
all angles of a triangles is equal to 180
x= 180° - (90° +40°)
x= 180° - 130°
x= 50°
Answer:
x=50°
Step-by-step 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°

Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)
