In the given figure, what is the measure of angle CPE?
Alina [70]

Answer:

Option B

Step-by-step explanation:

The 2 lines in this circle make a linear pair. this means that ∠CPE and ∠FPD are congruent this also means that their arcs are congruent. so you start out by setting 2x + 28 equal to 4x + 12. after you solve for x you should get x=8, inputting this into the angle equation (x + 60) and you should get 68

Solve and check the equation.<img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D%3D%5Cfrac%7B5x%7D%7B7%7D%20-43" id="TexFor
Y_Kistochka [10]

Answer:

x = 70

Step-by-step explanation:

Step 1: Simplify both sides of the equations.

  • \frac{x}{10} = \frac{5x}{7}-43
  • \frac{1}{10}x=\frac{5}{7}x-43

Step 2: Subtract 5/7x from both sides.

  • \frac{1}{10}x- \frac{5}{7}x = \frac{5}{7}x - 43 - \frac{5}{7}x
  • \frac{-43}{70}x = -43

Step 3: Multiply both sides by 70/(-43).

  • \frac{-43}{70}x * \frac{70}{-43} = -43*\frac{70}{-43}
  • x = 70

Step 4: Check if solution is correct.

  • \frac{(70)}{10}=\frac{5(70)}{7}  -43
  • 7 = \frac{350}{7} - 43
  • 7 = 50 - 43
  • 7 = 7

Therefore, x = 70.

PLEASE HELP! THIS IS DUE TOMORROW! Much appreciated.
denis23 [38]

Answer:

Step-by-step explanation:

1a) angle x and angle y are corresponding angles. Both angles lie on the same side of the transversal. Since the lines are parallel, the angles are equal.

1b) angle x and angle y are interior angles on the same side of the transversal. Since the lines are parallel, the angles are equal supplementary.

1c) angle x and angle y are corresponding angles. Both angles lie on the same side of the transversal. Since the lines are parallel, the angles are equal.

1d) angle x and angle y are alternate interior angles. They are between the parallel lines and alternate sides of the transversal. Since the lines are parallel, the angles are equal.
