Determine the value of (sine of 52 degrees, and 47 minutes). in this case, minutes are 1/60 of a degree. a. 0.3456926842 c. 0.4239584261 b. 0.9264835681 d. 0.7963540136

Option D.

Step-by-step explanation:

step 1

Convert to degrees

step 2

Using a calculator

Find the value of

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
