Answer:
Step-by-step explanation: A= (Pi) x r^2
Let's say that ST is side b
<span><span>Use the Law of Sines to find side b.</span><span>
b / sin(B) = a / sin(A)</span><span>
b / sin(59°) = 7 / sin(79°)</span><span>
b = (sin(59°) x 7) / sin(79°)</span><span>
b = 6.112
That is answer B.) 6.1 yards

Answers:
A)
C)
Step-by-step explanation:
<u>Part 1:</u>
We have the followig equation:

Calculating the least common multiple (l.c.m) in the denominator in the left side of the equation, being l.c.m=15:

Solving for the left part of the equation:

Operating with cross product:

Applying the distributive property:

Isolating
:

Dividing numerator and denominator by 11:
Hence, the correct option is A
<u>Part 2:</u>
We have the followig equation:

Operating with cross product:

Isolating
:
Hence, the correct option is C
