The answer will depend on whether the confidence interval is one-sided, or two-sided and, if two-sided, whether or not it is symmetrical. Symmetrical 2-sided: ±0.189
76 degrees
The other two angles could be 76-76 or they could be 28-124 .
-8 + √76 (≈ 0.7178) and -8 - √76 (≈ - 16.7178)

-77 + 77 = 0, and 0 + 76 = 76. You can take those two additions of 77 and 76, and add them together. 77 + 76 = 153, which is the answer.
0.33 * 76 = 25.08 or 10% of 76 = 7.6 * 3 = 22.8 (30%) 1% of 76 = 0.76 * 3 = 2.28 (3%) add together = 25.08

The smallest angle would be = 38 degrees. Proof: Base angles of an isosceles triangle must equ All angles of the triangle must add up to 180 degress considering that the known angle is not under 89 degrees the other two must equal, yet both add up to 76 degrees.

Add up the numbers, then divide by the number of numbers. Answer: 80
