Answer:
A. A reflection over the x-axis
Answer:
72°
Step-by-step explanation:
Let the 2 equal angles be x then the third angle is x + 18
The sum of the 3 angles in a triangle = 180°, thus
x + x + x + 18 = 180, that is
3x + 18 = 180 ( subtract 18 from both sides )
3x = 162 ( divide both sides by 3 )
x = 54
Hence
the largest angle = x + 18 = 54 + 18 = 72°
Answer:
A. 30
Step-by-step explanation:
Because it showed up the most
Let the number be x.
x*x*x = 54
x³ = 54 Taking cube roots
x = ∛54
x ≈ 3.780
