Question

prove the the some , Find the x​

Answer 1

Answer:

answer for the given problem is X=120°

Answer 2

Answer:

Step-by-step explanation:

First extent the lines BA and DC.

Then AE is a transversal which cuts BA and DC.

AND <BAH + <DHA =180⁰{CO-INTERIOR ANGLE}

therefore, <DHA= 180⁰-105⁰

= 75⁰

<DHA+<DHE =180⁰{LENIER PAIRS}

<DHE = 180⁰-75⁰

= 105⁰

<CHE+<HEC+<ECH = 180⁰ {ANGLE SUM PROPERTY}

105⁰ + 15⁰ + <ECH =180⁰

120⁰ + <ECH = 180⁰

<ECH = 180⁰- 120⁰

= 60⁰

<ECH + <DCE = 180⁰{LENIER PAIRS}

60⁰+ <DCE = 180⁰

<DCE = 180⁰- 60⁰

= 120⁰

Therefore, x = 120⁰
