An angle measures 64.8° less than the measure of its complementary angle. What is the measure of each angle?
kirill115 [55]

Answer:

<u>77.4 degrees and 12.6 degrees</u>

Step-by-step explanation:

Let the angles be x and x - 64.8.

Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :

x + x - 64.8 = 90

2x = 154.8

x =  <u>77.4 degrees</u>

x - 64.8 = 77.4 - 64.8 = <u>12.6 degrees</u>

What point would be reflected across the y-axis to ( − 3, − 9) ?
Aloiza [94]

Answer:

(-3, 9)

Step-by-step explanation:

If a point was reflected across the y-axis, then the y-coordinate would change signs (from negative to positive or from positive to negative). Using this, we could find the original point by changing the sign of the y-coordinate. As you may already see, this is really just reflecting the point across the y-axis again. By doing this, you get the point (-3, 9).

The point would be (-3, 9).

I hope this helps. :)
