Answer

\( x = \frac{23}{11} \)

Solution

To solve for \( x \) in the given angles, we can use the fact that the sum of the angles in triangle \( RQP \) is \( 180^\circ \). The angles given are: - \( m \angle R Q G = 6 + 5x \) - \( m \angle G Q P = 121^\circ \) - \( m \angle R Q P = 17x + 7 \) We can set up the equation: \[ m \angle R Q G + m \angle G Q P + m \angle R Q P = 180^\circ \] Substituting the expressions for the angles, we have: \[ (6 + 5x) + 121 + (17x + 7) = 180 \] Now, let's simplify this equation step by step: 1. Combine like terms: \[ 6 + 121 + 7 + 5x + 17x = 180 \] \[ 134 + 22x = 180 \] 2. Subtract 134 from both sides: \[ 22x = 180 - 134 \] \[ 22x = 46 \] 3. Divide by 22: \[ x = \frac{46}{22} \] \[ x = \frac{23}{11} \] Thus, the value of \( x \) is \( \frac{23}{11} \).

To solve for \( x \), we can use the fact that the angles in triangle \( RQP \) add up to \( 180^\circ \). We know: \[ m \angle RQP + m \angle QRP + m \angle QPR = 180^\circ \] From the problem, we have: - \( m \angle RQP = 6 + 5x \) - \( m \angle QRP = 121^\circ \) - \( m \angle QPR = 17x + 7 \) Substituting these values into the angle sum equation gives us: \[ (6 + 5x) + 121 + (17x + 7) = 180 \] Now combine like terms: \[ (5x + 17x) + (6 + 7 + 121) = 180 \] \[ 22x + 134 = 180 \] Next, we isolate \( x \) by subtracting 134 from both sides: \[ 22x = 180 - 134 \] \[ 22x = 46 \] Now, divide by 22 to solve for \( x \): \[ x = \frac{46}{22} = \frac{23}{11} \approx 2.09 \] So, the value of \( x \) is \( \frac{23}{11} \) or approximately \( 2.09 \).
