Given: ∠WXY and ∠YXZ are supplementary angles and ​ m∠WXY=75° ​ Prove: m∠YXZ=105°
mestny [16]

Answer:

m∠WXY + m∠YXZ = 180°

Replacing with the real values:

75° + m∠YXZ = 180°

m∠YXZ = 180° - 75°

<u>m∠YXZ = 105°</u>

Step-by-step explanation:

1. Let's review all the information provided to us to answer the question correctly:

∠WXY and ∠YXZ are supplementary angles

m∠WXY=75°

2. Prove : m∠YXZ=105°

Let's recall that supplementary angles are those angles whose sum is 180 degrees. Therefore,

m∠WXY + m∠YXZ = 180°

Replacing with the real values:

75° + m∠YXZ = 180°

m∠YXZ = 180° - 75°

<u>m∠YXZ = 105°</u>
