Answer:

x=15

Step-by-step explanation:

well by angles in parallel lines

angle 1 is equal angle 2

so we have

7x=5x+30\\\\7x-5x=30\\\\2x=30\\\\x=15

Answer:

15

Step-by-step explanation:

Since angles 1 and 2 are known as "alternate interior angles", they are equal to each other.

Since they are equal, we can set the equations equal to each other as well.

7x = 5x + 30

-5x  -5x

2x = 30

x = 15

Please help idk what I’m doing

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)

The amount of a chemical solution is measured to be 2 liters. What is the percent error of the measurement?
dezoksy [38]
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%
