Answer:
Angle EDC = Angle ADC
(Reflexive property)
ABD ~ ECD because all angles are congruent
If two are congruent, third one has to be as well since total angle is 180 each
WOW I'm in middle school too and we don't even do this stuff
Answer:
13
Step-by-step explanation:
You use pemdas to figure this out, so you do whats in the parentheses first, 2x-6, but instead you do 2(4)-6 and when your solving stuff in the parentheses you apply pemdas again to figure out what to do, so you multiply 2x4 first bcz m is before s, and then you do 8-6 bcz there's nothing else to do in the parentheses. now that your done with the parantheses you currently have 3x3 +2(2). now you dont have p or e but you do have m and when you have multiple instances of multiplication you do it left from right, so you do 3x3 first and get 9 and then you do 2x2 and get 4. now you have 9+4 and since you have nothing else to do you add and you get 13.
