A triangular frame has sides that measure 15'-7",20'-4" and 26'-2". What is the total length of three sides?
meriva

Answer:

The total length of three sides is 62'-1"

Step-by-step explanation:

We know that 1 foot = 12 inches and 1' = 12''

Part 1)

We also know that side 1=15'-7", side 2=20'-4", side 3=26'-2"

To find the total length of three sides sum the three sides

So the total length=side 1+side 2 +side 3

Now we substitute

Total length=15'-7"+20'-4"+26'-2"

Total length=(15'+20'+26')+(7"+4"+2")

Total length=(61')+(13")

Remember that 12"=1'

13"=12"+1"=1'+1"

Substitute again

Total length=(61')+(1'+1")

Total length=(62')+(1")---------> 62'-1"

<u>Therefore the answer is the total length of three sides is 62'-1"</u>

Given cscx =-5/2 between 270 and 360 find sin2x
ICE Princess25 [194]
Hello : 
cscx = -5/2
1/sinx =-5/2
sinx=-2/5
sin²x+cos²x=1
4/25+cos²x=25/25
cos²x = 21/25
between 270 and 360 : cosx > 0          cosx=(<span>√21)/5
but : sin2x =2sinx cosx
       sin2x = 2(-2/5)(</span>(√21)/5)
       sin2x = (-4√21)/25
