3-83.

Use your Trig Table Graphic Organizer from problem 3-82 to help you determine the value of each variable below.

  1. A right triangle with a base of x and height of 95. 79 degrees angle is in between the base and hypotenuse and theta angle is in between the height and hypotenuse.

    By the Triangle Angle Sum Theorem,

  1.  A right triangle with a base of 40 and height of 40. a angle is in between the base and hypotenuse and b angle is in between the height and hypotenuse.

    Notice that the legs of the right triangle are the same lengths.

  1. A right triangle with a base of 70 and height of y. 22 degrees angle is in between the height and hypotenuse.

    Look at the hints in part (a).
