Question

label the sides and angle and calculate the missing values in the triangle:
h = 1.93
0 = 38.5°
a = 1.51

Explanation:

Step1: Use sine function

In a right - triangle, \(\sin\theta=\frac{O}{H}\). Given \(\theta = 38.5^{\circ}\) and \(H = 1.93\).

Step2: Calculate \(O\)

\(O=H\times\sin\theta\). Substitute \(H = 1.93\) and \(\theta=38.5^{\circ}\) (\(\sin(38.5^{\circ})\approx0.623\)).
\(O = 1.93\times0.623\approx1.20\)

Answer:

\(O\approx1.20\)
