Answer:
B. ∆XYZ, in which m∠X = 10° and m∠Z = 25°
Explanation:
∆ABC
m∠A = 10°
m∠B = 145°
m∠C = 180° - (m∠A + m∠B )
= 180° - (10° + 145°)
= 180° - 155°
m∠C = 25°
∆XYZ
m∠X = 10°
m∠Z = 25°
m∠Y = 180° - (m∠X + m∠Z)
= 180° - (10° + 25°)
= 180° - 35°
m∠Y = 145°
so,
m∠A = m∠X = 10°
m∠C = m∠Z = 25°
m∠B = m∠Y = 145°
