Please help me with this last math problem!! No links please!! Will give brainliest if correct!! It's due tonight!! :)
1 answer:
Since it’s indicated that BC and AD are congruent, you can set the two sides/equations equal to one another: 3x+3=x+21 Then, you can solve for x: 3x+3=x+21 2x=18 x=9 Plugging in 9 into either equation of BC or AD should give you 30 for both sides: 3(9)+3=30 (9)+21=30 For CD, you can also plug in 9 for x: 2(9)-9=18 Since AB and CD are labeled as congruent, both sides are 18. x=9 AB=18 BC=30 CD=18 AD=30
