Answer:
Step-by-step explanation:
Pitagora theorem is 14^2=9^2+x^2
-9^2 -9^2
so the equation is
x^2=14^2-9^2
Answer:
Step-by-step explanation:
<em>m∠D</em> = 90° - 51° = <em>39°</em>
sin E =
⇒ DE = DF × sin E
<em>DE</em> = 18 sin51° ≈ <em>14.0 ft.</em>
cos E =
⇒ EF = DF × cos E
<em>EF</em> = 18 × cos51° ≈ <em>11.3 ft.</em>
