28. Which of the following is the correct measure of
FrozenT [24]

Answer:

  • D) 44°

Step-by-step explanation:

According to the diagram we observe:

  • ∠ACD is the exterior angle of triangle ABC.

As we know the exterior angle is same as the some of the remote interior angles.

It can be shown as:

  • m∠ACD = m∠CAB + m∠CBA

Substitute the values and solve for x:

  • 5x - 18 = 3x - 2 + x + 14
  • 5x - 18 = 4x + 12
  • 5x - 4x = 12 + 18
  • x = 30

Find the measure of m∠ABC:

  • x + 14 = 30 + 14 = 44

The matching <u>answer</u> choice is D.

Can someone help me pls!
eduard

This question is about how transformations can affect graphs.

First, we'll want to get rid of that -4 on the function of F.

So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph x^2.

Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.

Finally, we can move the function of by \frac{2}{3} because the d value is positive, meaning that we move the graph up.

Hope this helps.

頑張って!
