Answer

$a \approx 188$ cm

Work Step by Step

RECALL: (1) $\sin{\theta} = \dfrac{\text{opposite side}}{\text{hypotenuse}}$ (2) $\cos{\theta} = \dfrac{\text{adjacent side}}{\text{hypotenuse}}$ (3) $\tan{\theta} = \dfrac{\text{opposite side}}{\text{adjacent side}}$ Use (3) above to obtain: $\tan{37^o}=\dfrac{a}{250} \\250(\tan{37^o})=a$ Use a calculator in DEG mode to obtain $\\188.3885125 = a \\a \approx 188$ cm
