Answer:
m∠1 = 39.5°
m∠2 = 39.5°
m∠3 = 50.5°
m∠4 = 50.5°
Step-by-step explanation:
m∠1 = 39.5° (Given)
m∠2 = m∠1 = 39.5° (∠1 ≅ ∠2)
m∠3 = 90° - 39.5° = 50.5° (∠1 and ∠3 are complementary)
m∠4 = m∠3 = 50.5° (∠1 ≅ ∠2, ∠2 and ∠4 are complementary)
The arc is called B) Circle
Answer:
s= 15 (nearest integer), 14.8 (to nearest 10ths)
Step-by-step explanation:
here you need to apply the cosine rule,

substituting the values,
u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)
