To solve for \( x \) given that angles \( \angle MAT \) and \( \angle TAH \) are supplementary, we know that the sum of the angles is equal to \( 180^\circ \).
Given: \[ \angle MAT = (6x - 6)^\circ \] \[ \angle TAH = (4x - 14)^\circ \]
Since they are supplementary: \[ (6x - 6) + (4x - 14) = 180 \]
Combining like terms, we get: \[ 10x - 20 = 180 \]
So, the correct equation to solve for \( x \) is: \[ 10x - 20 = 180 \]
The expression that corresponds to this is: 10x°−20°=180°.
