Quadrilateral A B C D is shown. The uppercase right angle, angle A, is 79 degrees. What are the remaining angle measures if the figure is to be a parallelogram? m∠B = ° m∠C = ° m∠D = °

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

there are no short passages to look at

36 is the final answer! : )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
