The calculated probability (1.18%) is way less than the advocate's claim.
Hence, we do not believe the claim.
Answer:
Step-by-step explanation:
This means that <C and <F are congruent.
So 2x - 15 = x + 15 Add 15 to both sides
2x-15+15=x+15+ 15
2x = x + 30 Subtract x from both sides
2x-x=x-x+30
x = 30
I've taken the bottom 2 angles to be equal. The lettering says they
are
P- (-1,7) Q-(2,7) R-(7,-3) S-(-4,-4)
The answer to this would be
H. 30
I.48
