Two yards is equal to six feet, one yard is 3 feet
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
we have

The cos(A) is negative, that means that the angle A in the triangle ABC is an obtuse angle and the value of the sin(A) is positive
The angle A lie on the II Quadrant
step 1
Find the measure of angle A

using a calculator

step 2
Find the sin(A)
we know that

substitute the value of cos(A)




step 3
Find tan(A)
we know that

substitute the values

Simplify

Fraction = 4/7
Step by step Explanation
Let the denominator be x.
Numerator = 3 less than denominator
denominator = x
Numerator = (x – 3)
Now, Adding 5 to denominator
adding 2 to numerator.
Numerator = (x – 3 + 2)
Denominator = (x + 5)
(x – 3 + 2)/(x + 5)
According to the question
(x – 3 + 2)/(x + 5) = 1/2
(x – 1)/(x + 5) = 1/2
2(x – 1) = 1(x + 5)
2x – 2 = x + 5
2x – x = 5 + 2
x = 7
So,
=> Denominator x = 7
=> Numerator (x – 3) => (7 – 3) = 4
= > Fraction = 4/7
