Answer:
x positive, y negative
Step-by-step explanation:
-60 is the 4th quadrant of the unit circle ( negative angles go clockwise from 0), so the x value is positive and the y value is negative.
Answer: r = 7
Step-by-step explanation:
Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation.
Answer:
Always
Step-by-step explanation:
Right triangles are always similar.
All right triangles have a 90 degree angle.
This means that, they would all look visually similar because of the 90 degree angle.
One of the requirements of a rectangle is that it must have four right angles ( a right angle is 90 degrees) so you just multiply 90 by 4 and you get 360 degrees
-4g + 12 = 16 then -12 on the both side
-4g = 4 then divided by -4, you will get g = -1
