Trigonometry: Sine Bar Applications discusses sine bars and the trigonometry required to use them. Sine bars are used when an angle needs to be machined, measured, or inspected. Sine bars are used ...
Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...
Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...
