Answer:

Cos x

Step-by-step explanation:

HINT:

1 -   Sin² x = Cos² x

Sec x = \frac{1}{Cos x}

Sec x - Sec x*(Sin x)² = Sec x (1 - Sin² x)

                                  = Sec x * Cos²x

                                  = \frac{1}{Cos x}*Cos^{2} x

                                  = Cos x

Answer:

B.50

Step-by-step explanation:

The two angles form a right angle ( indicated by the little square )

Right angles have a measure of 90 degrees

Hence, x + 10 + 30 = 90

( Note that we just created an equation that we can use to solve for x )

We now solve for x using the equation we created

x + 10 + 30 = 90

Combine like terms

x + 40 = 90

Subtract 40 from both sides

x = 50

pshichka [43]

Experimental Probability = 2/3

To find the experimental probability that the tack lands point-up for student 4, we can use the following equation

\frac{Point-up}{Attempts}\\\frac{4}{6} or\frac{2}{3}

If this helped you a Brainliest would be appreciated!
