A right triangle (Fig. 1.8) has sides of length x = 4.5 m and y = 3.7 m.?

(a) Find the value of r (the length of the hypotenuse).?

(b) Find the values of the interior angles. Express your answers in degrees and radians.?

(c) Find the sine, cosine, and tangent of the smaller interior angle.?

(d) Find the sine, cosine, and tangent of the larger interior angle.

Figure 1.8

x2 + y2 = r2 y Right angle = 90

x2 + y2 = r2 y Right angle = 90
