Use tangent.

tangent=\dfrac{opposite}{adjacent}

\tan(m\angle F)=\dfrac{DE}{EF}

We have:

m\angle F=32^o,\ DE=15

Substitute:

\tan32^o=\dfrac{15}{EF}\\\\\tan32^o\approx0.6249\\\\\dfrac{15}{EF}=0.6249\\\\\dfrac{15}{EF}=\dfrac{6249}{10000}\ \ \ \ |\text{cross multiply}\\\\6249EF=150000\ \ \ \ |\text{divide both sides by 6249}\\\\EF\approx24

<h3>Answer: 24.0</h3>

How do you write 32,005,008 in expanded form
Karolina [17]
To write 32,005,008 in expanded form, you write it out like this: <span>32,005,008 = 30,000,000 + 2,000,000 + 5,000 + 8.

I know this because I learned it in 3rd grade at school.

Hope I helped!
