Answer:
Can not be determined (CNBD)
Step-by-step explanation:
In the given triangle ACI,
M is the mid point of CI, So we have
CM= MI
also AM=AM ( reflexive property )
So far we have two pairs of corresponding sides are congruent in ΔCAM and ΔIAM
To prove that ΔCAM≅ΔIAM using SSS (side side side ) congruence theorem
we should have AC =AI , but it is not given,so we can not say that AC=AI
To prove that ΔCAM≅ΔIAM using SAS (side angle side ) congruence theorem
we should have ∠AMC=∠AMI, but it is not given,so we can not say that ∠AMC=∠AMI
We can not determine that ΔCAM is congruent to which triangle
Hence the answer is Can not be determined (CNBD)
Answer:
Step-by-step explanation:
∠E = ∠G
∠D= ∠F because it’s a parallelogram ==> D=F=2x+12 and E=G=5x
5x+2x+12=180
7x=168
X=24
Solution 2:
2*5x+2*(2x+12)=360
10x+4x+24=360
14x=360-24=336
X=336/14
X=24
I think this is the answer:
The associative property states that we can add numbers in any way we want to still get the same sum, so the parenthesis here can essentially be tossed out to get 3x+2-5=3x-3. However, make sure, for example, that you don't add x and 1 together in 3(x)+1 as you still have to multiply the x with 3 before adding the 1 according to PEMDAS
