Question
directions: if ( l parallel m ), solve for ( x ) and ( y ).
9.
( (9x + 25)^{circ} )
( (13x - 19)^{circ} )( (17y + 5)^{circ} )
Step1: Encontrar el valor de \(x\)
Como \(l\parallel m\), los ángulos \((9x + 25)^{\circ}\) y \((13x-19)^{\circ}\) son ángulos suplementarios. Entonces:
$$

$$
Step2: Encontrar el valor de \(y\)
Sustituimos \(x = 9\) en \(9x + 25\): \(9\times9+25=81 + 25=106^{\circ}\)
Como \(l\parallel m\), el ángulo \(106^{\circ}\) y \((17y + 5)^{\circ}\) son ángulos alternos internos. Entonces:
$$
LATEXBLOCK1
$$
