Determine the length of chord BC. 1) 17.45 2) 30.96 3) 67.06 4) 33.53
1 answer:
Answer:
33.53
Step-by-step explanation:
OB is a radius of the circle, and OC is also a radius of the circle, so both are equal length. That makes ΔOBC an isosceles triangle.
If we cut ΔOBC in half, the angle formed is 125° / 2 = 62.5°.
Therefore:
sin 62.5 = (x/2) / 18.9
x = 37.8 sin 62.5
x ≈ 33.53

Answer is 14 due to PEMDAS
Answer:
has greater absolute value, so the sum is positive.
Step-by-step explanation:
Find the exact answer to see if your estimate is reasonable.
simple interest = principal × rate × time in years
= 3450 × (2/100) × ( 1.25)
= 3450 × 0.02 × 1.25
= 86.25
