How do I know?:
put this function in graphing calculator
And if you don't have a graphing calculator, then calculate it out bu yourself:
(x + 1)(x − 1)(x − 7) = 0
Answer:I think it’s c
Step-by-step explanation:
4/5 is the same as 80% or .80, so it's larger than 76% and .77
The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
<h3>How to determine the missing sides and angles</h3>
In this question we have a triangle with a known <em>side</em> lengths and two known <em>angle</em> measures. First, we find the missing angle by <em>Euclidean</em> geometry:
C = 180° - 94° - 23°
C = 63°
Lastly, we determine the <em>missing</em> sides by law of sines:

b ≈ 28.084

c ≈ 25.084
The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
