In the figure, AB is a diameter of circle P. What is the arc measure of AD in degrees?
fiasKO [112]

The arc measure of AD in degrees is 43 degrees.

<u>Step-by-step explanation</u>:

  • The angle measure of the straight line is 180°.
  • ∠APD + ∠DPC + ∠CPB = 180°

⇒ (7x+1)° + 90° + (9x-7)° = 180°

⇒ 16x + 84° = 180°

⇒ 16x = 96°

⇒ x = 96/16

x = 6

Substitute x=6 for angle ∠APD = (7x+1)°

∠APD = 7(6)+1 = 43°

The arc measure of AD in degrees = 43 degrees.

Does the order in which the two transformations in a composite transformation affect the final
kap26 [50]

The order in which the two transformations in a composite transformation affect the final answer

<h3>How to determine the composite transformation?</h3>

To determine if order matters or not, I will use the following example and illustration.

Let the coordinate of point A be:

A = (2, 5)

Perform the following transformations:

  • Translate by (x, y + 1)
  • Dilate by a scale factor of 2

First order: Translation before dilation

The translation by (x, y + 1) would give:

A' = (2, 5 + 1)

A' = (2,6)

The dilation by a scale factor of 2 would give

A" = 2 * (2,6)

A" = (4,12)

Second order: Dilation before translation

The dilation by a scale factor of 2 would give

A' = 2 * (2,5)

A' = (4,10)

The translation by (x, y + 1) would give:

A'' = (4, 10 + 1)

A'' = (4,11)

See that the final coordinates in both orders are not the same.

Hence, the order in which the two transformations in a composite transformation affect the final answer
