Question

what is the measure of ∠xbc?

1. ( mangle xbc = mangle bac + mangle bca )
2. ( 3p - 6 = p + 4 + 84 )
3. ( 3p - 6 = p + 88 )
4. ( 2p - 6 = 88 )
5. ( 2p = 94 )

( mangle xbc = square^circ )

Explanation:

Step1: Solve for \( p \) from \( 2p = 94 \)

Divide both sides by 2: \( p=\frac{94}{2}=47 \)

Step2: Substitute \( p \) into \( 3p - 6 \)

Substitute \( p = 47 \) into \( 3p - 6 \): \( 3\times47 - 6=141 - 6 = 135 \)

Answer:

\( 135 \)
