Answer:
m∠FXM = 24°
Step-by-step explanation:
This problem has a lot of extra data that has no relation to the question. You can basically ignore any business about isosceles triangles and congruent segments.
__
The only thing you need to know is the angle sum theorem:
m∠FXM + m∠MXA = m∠FXA
Filling in the numbers, you get ...
m∠FXM + 72° = 96°
m∠FXM = 96° -72° = 24°
The measure of angle FXM is 24°. (matches choice A)
Answer:
20°
Step-by-step explanation:
A triangle = 180°
∴ 180° -120°-40°
=20°

The complete question in the attached figure
we know that
2 liters may be 1.5 to 1.9 rounded up to 2
or 2.1 to 2.4 rounded down to 2
the biggest percent error would be between 2 and 1.5, which is a volume error of 0.5 liters
2 - 1.5 = 0.5 liters
percent error = (absolute error / quantity) * 100
percent error = [0.5/2] * 100% = 0.25 * 100% = 25%
the answer is the option C) 25%
