Step-by-step explanation:

<u>Step 1:  List out all of the formulas for the trigonometric functions </u>

<em>sin(x) </em>= opposite/hypotenuse

<em>cos(x) </em>= adjacent/hypotenuse

<em>tan(x)</em> = opposite/adjacent

<u>Step 2:  Find the value of h </u>

cos(68) = 13/unknown is FALSE

cot(68) = 13/h is FALSE

sin(68) = h/unknown is FALSE

tan(68) = h/13 is TRUE

Answer: The correct option would be D

ladessa [460]

Answer:

-(-4)(-6)*3/5(10+15)

when there is a (-) in front of an expression in parentheses, change the sing of each term in the expression.

4*(-6)*3/5*(10+15)

Add the numbers (10+15)

4(-6)*3/5*25

multiplying an odd number of negative terms makes the product negative

-4*6*3/5*25

reduce the number with the greatest common factor 5

-4*6*3*5

calculate the product

Use the formula for the difference of cubes to show that 125 - 27 = 98
IrinaVladis [17]

The formula is

a^3 - b^2 = (a - b)(a^2 + ab + b^2)  so plugging in  the given values:-

a = cube root of 125 = 5 and b = cube root of 27 = 3 ,  we get:-

125 - 27 = (5 - 3)(5^2 + 5*3 + 3^2)

= 2 * 49

= 98   answer
