Answer:
E = $385
Step-by-step explanation:
35 x 11 = 385
Subtract the 2 on both sides to get -4x=-5x+7, then add -5 on both sides and get 1x=7 then divide 1 on both side to get x=7
Answer: C. 124
Step-by-step explanation:
In parallelograms, any two consecutive interior angles add to 180 degrees. CDA and BCD are consecutive interior angles. Since the measure of angle CDA is 56 and the sum of CDA and BCD equal 180, then to find the value of BCD, evaluate 180-56.
180 - 56 = 124
