bija089 [108]
There are 2 fractions you could write, 2/4, which would be 6/12, or 1/4, which would be 3/12
as you can see both are less than 7/12

Finding Hypotenuse Lengths. Find the length of the hypotenuse.
ioda

Answer:

11) \frac{3\sqrt{5}}{2}

12) 4\sqrt{5}

13) 22

14) 18

15) 2

16) 24\sqrt{3}

Step-by-step explanation:

For these problems I used the pythagorean theorem: a^{2}+ b^{2}= c^{2} and SOHCAHTOA

Sin = \frac{opposite}{hypotenuse}

Cos = \frac{adjacent}{hypotenuse}

Tan = \frac{opposite}{hypotenuse}

11)

First find the length of the bottom side by using Cos

cos(60)=\frac{x}{3}

3(cos(60))=x

1.5=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

3^{2}+ 1.5^{2}= c^{2}

9+2.25=c^{2}

\sqrt{11.25}=\sqrt{c^{2}}

\frac{3\sqrt{5}}{2}

12)

Find the length of the bottom side using Cos

cos(60)=\frac{x}{8}

8(cos(60))=x

4=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

8^{2}+ 4^{2}= c^{2}

64+16=c^{2}

\sqrt{80} =\sqrt{c^{2} }

4\sqrt{5}

13)

Find the length of the other side by using Tan

tan(30)=\frac{x}{11\sqrt{3} }

11\sqrt{3}* (tan(30)=x

11=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

(11\sqrt{3}) ^{2}+ 11^{2}= c^{2}

363+121=c^{2}

\sqrt{484} =\sqrt{c^{2}}

22

14)

(This is probably an easier way to do these problems)

Find the hypotenuse by using Cos (\frac{adjacent}{hypotenuse})

cos(60)=\frac{9}{x}

cos(60)x=9

x=\frac{9}{cos(60)}

x=18

15)

Find the hypotenuse using Sin (\frac{opposite}{hypotenuse})

sin(30)=\frac{1}{x}

sin(30)x=1\\x=\frac{1}{sin(x)}

x=2

16)

Find the hypotenuse using Cos (\frac{adjacent}{hypotenuse})

cos(60)=\frac{12\sqrt{3} }{x}

cos(60)x=12\sqrt{3}

x=\frac{12\sqrt{3} }{cos(60)}

x=24\sqrt{3}
