Bcde is a parallelogram. what is the measure of ∠bec? enter your answer in the box.

80°

Step-by-step explanation:

∠CBE = 60°

∠BCE = ∠CED = 40°

∠BCE + ∠CBE + ∠BEC = 180°     Substitute values

∠BCE + 60° + 40° = 180°

∠BCE + 100° = 180°                     Subtract 100° from each side

∠BCE = 80°

could you reply to this with the question so i can ?

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
