Find the value of sec theta, if cos theta =2/19; 0degrees less than and equal to theta less than and equal to 90 degrees.

a) 2/19
b) -19/2
c) -2/19
d) 19/2

19/2

Step-by-step explanation:

This problem is a problem desgined to test your basic understanding of Trigonomic functions and there applictoins.

Sec theta is the inverse of cos theta, which means sec theta is equal to adjecent / opposite.

They already gave you cos theta which is 2/19

We should know that from 0 to 90 degrees, sec theta is postive.

so sec theta is 19/2

Step-by-step explanation:

The translation vector < 4, - 2 > means each point is being moved 4 units to the right and 2 units down.

X(0, 3) > X' ( 0 + 4, 3 - 2 ) = X'(4, 1)

Y( - 1, 1) > Y' ( - 1 + 4, 1 - 2 ) = Y'(3, - 1)

Z( - 3, 4) > Z' ( - 3 + 4, 4 - 2 ) = Z'(1, 2)
