It seems there are always three pairs: SSS, side side side; SAS, side angle side; ASA, angle side angle.
For a right triangle (HL, LL) it seems there are only two items needed, but that's because we already know one angle (it's right).
Once we have congruent triangles, all the corresponding parts are congruent. That's three sides and and three vertices, so I'd answer six. Of course almost everything about the triangles is the same, the area, the perimeter, etc.
An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side?
Explain how you would define a variable for this problem.
The answer is D

that's the answer the negative sign affects what's in the bracket
Answer: (84.876, 87.124)
Step-by-step explanation:
Confidence interval for population mean if population standard deviation is unknown:
, where n= sample size
s= sample standard deviation
= sample mean
significance level
= critical-t value
Given: n= 64
Degree of freedom = n-1 = 63
s= 4.5
= 86
0.05
= 1.9983
Now, the required 95% confidence interval would be:
The 95% confidence interval for the population mean μ is between: (84.876, 87.124)
