Answer:
155.45 cm
Step-by-step explanation:
Given: Length of side x (opposite)= 89.75 cm
Angle is 30°
Lets use tangent rule to find the value of y (adjacent).
[tex]tan\theta = \frac{opposite}{adjacent}[/tex]
∴ [tex]tan 30= \frac{89.75}{y}[/tex]
Using trigonometry table
⇒ [tex]\frac{1}{\sqrt{3} } = \frac{89.75}{y}[/tex]
Now, cross multiplying both side
⇒ y= [tex]89.75\times \sqrt{3} = 155.45[/tex]
∴ 155.45 cm is the length of side y.
