Answer:
Well, if we know that an obtuse angle is an angle greater than 90 degrees, and that a triangle's angles MUST sum up to 180 degrees and contain three angles. Then it logically follows that there's no way for a triangle to have 3 angles AND have two of the three be greater than or equal to 90 degrees as the remaining angle would have to be zero degrees or some "negative angle"- which I am pretty sure doesn't exist lol! As for a proof, I think you can cook up something with what I have given you so far :)
Answer:8
Step-by-step explanation:
4 to the second = 4 times 4 = 16
16 divided by 2 = 8
The first 15 digits of Pi are:

Answer:
1. BC≅DC ; AC≅EC
2. ∠BCD≅∠ACE and ∠BCA≅∠DCE
3. SAS (side angle side)
Step-by-step explanation:
The circumference is the diameter times pi.
![d=60 \ [cm] \\ \\ C=60\pi \approx 60 \times 3.14=188.4 \approx 188 \ [cm]](https://tex.z-dn.net/?f=d%3D60%20%5C%20%5Bcm%5D%20%5C%5C%20%5C%5C%0AC%3D60%5Cpi%20%5Capprox%2060%20%5Ctimes%203.14%3D188.4%20%5Capprox%20188%20%5C%20%5Bcm%5D)
The answer is D.
