Answer:
Step-by-step explanation:
<u>Find the measure of arc BD</u>
- m∠A = 1/2(arc BC - arc BD)
- 2*36° = 150° - arc BD
- arc BD = 150° - 72° = 78°
<u>Find the measure of arc DC</u>
- arc BD + arc BC + arc DC = 360°
- arc DC = 360° - (150° + 78°) = 360° - 228° = 132°
Correct choice is B

Answer:
y=70°
z= 60°
w= 70°
Step-by-step explanation:
Since the two triangles are similar, we know that all of the corresponding angles must be the same. On the triangle on the left, we can see that the angle formed between sides AB and AC is 60°. This means that the same angle is formed at Z, which is in the same location on the triangle to the right. From there, we can find the missing angle, W, from the difference of 180°.
180°-50°-60°=70°.
The same way we found Z, we can also find Y, since it has to be the same as W.
