## Trigonometry (11th Edition) Clone

1. Split an isosceles triangle into two equal right triangles, with angle $34^{\circ}22'$ (halved angle of the isosceles triangle ) and opposite side $92.1 cm$ (halved base of the isosceles triangle ) 2. To find x (adjacent) use definition of trig function tangent $\tan 34^{\circ} 22 ' = \frac{92.1}{x}$ $x\approx 134.7$ [4 significant figures as it is in a given side]
