Two complementary angles have measures ( 4x) and ( 2x). What is the value of x and the two angle measures?

x =, ( 4x ) =__, and (2x ) = __

1 answer

Complementary angles are angles that sum up to \(90^\circ\).

Given the angles \(4x\) and \(2x\), we can set up the equation:

\[ 4x + 2x = 90 \]

Combining like terms:

\[ 6x = 90 \]

To solve for \(x\), divide both sides by 6:

\[ x = \frac{90}{6} = 15 \]

Now that we have the value of \(x\), we can find the measures of the angles:

  1. For the angle \(4x\):

\[ 4x = 4 \times 15 = 60^\circ \]

  1. For the angle \(2x\):

\[ 2x = 2 \times 15 = 30^\circ \]

Thus, we have:

  • \(x = 15\)
  • \(4x = 60^\circ\)
  • \(2x = 30^\circ\)

In summary:

  • \(x = 15\)
  • \(4x = 60^\circ\)
  • \(2x = 30^\circ\)
