Review the Math Notes box in this lesson.

  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.

    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).
