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"

Therefore the answer is the total length of three sides is 62'-1"

What is the length of SR ? 9 units 12 units 15 units 18 units

astraxan [27]

Answer: THe correct option is (C) 15.

Step-by-step explanation: We are given to find the length of SR in the right-angled triangle SRQ as shown in the figure.

Since RT is perpendicular to the hypotenuse SQ, so triangle RTQ and SRT are also right-angled triangles at angle RTQ and RTS respectively.

Also, RQ = 20 units and TQ = 16 units.

Using Pythagoras theorem in triangle RTQ, we have

$RQ^2=RT^2+TQ^2\\\\\Rightarrow RT=\sqrt{RQ^2-TQ^2}\\\\\Rightarrow RT=\sqrt{20^2-16^2}\\\\\Rightarrow RT=\sqrt{144}\\\\\Rightarrow RT=12.$

Now, since RT is perpendicular to the hypotenuse of ΔRST, so we get

$ST\times TQ=RT^2\\\\\Rightarrow RS\times 16=144\\\\\Rightarrow RS=\dfrac{144}{16}\\\\\Rightarrow RS=9.$

Again, using Pythagoras theorem in right-angled triangle RST, we get

$SR^2=RT^2+ST^2\\\\\Rightarrow SR=\sqrt{144+81}\\\\\Rightarrow SR=\sqrt{225}\\\\\Rightarrow SR=15.$

Thus, the length of SR is 15 units.

Option (C) is CORRECT.
