Q:-If the perimeter of an isosceles triangle is 83 cm. and its base is 23 cm. Find the measure of its equal sides.
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u><u> </u> As we know that Perimeter is the sum of all sides.
- Let the both side be x
- 83 = 23 + (x + x)
- 83 - 23 = 2x
- 60 = 2x
- 30 = x
Other two sides are 30 cm.
10.The perimeter of a rhombus is 5.6 cm. Find its side.
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u><u> </u> As we know that
Side of Rhombus = Perimeter/4
- Side = 5.6/4
- Side = 1.4 cm
- Side is 1.4 cm
11.The perimeter of a rectangle is equal to that of a square with side 17 m. If the length of the
The perimeter of a rectangle is equal to that of a square with side 17 m. If the length of therectangle is 26 m. What is its breadth ?
<u>Answer</u><u>:</u><u>-</u> Perimeter of square = 4 × s
- Perimeter = 4 × 17
- Perimeter = 68 cm
Now,
- Perimeter of rectangle = 2(l + b)
- 68 = 2(26 + b)
- 68/2 = 26 + b
- 34 = 26 + b
- 34 - 26 = b
- 8 = b
- b=8
12.What is the cost of fencing a rectangular field of length 16 m and breadth 11 m at the rate of 12 per m.
<u>Answer</u><u>:</u><u>-</u> Perimeter = 2(l + b)
- Perimeter = 2(16 + 11)
- Perimeter = 2(27)
- Perimeter = 54 cm
Now,
- Total cost = 54 × 12
- Total cost = ₹648.
Answer:
67.53 kiloliters.
Step-by-step explanation:
We have been given that the capacity of the molten sea, a furnishing of the temple, is given as 2000 baths.
First of all, we will convert 2000 baths into gallons by multiplying 2000 with 8.92.
We know that 1 gallon equals 0.00378541 kiloliters, so we will multiply 17,840 by 0.00378541.
Therefore, the Molten sea hold 67.53 kiloliters.
We can find 20% of $7.95 as shown below:
Therefore, 20% of $7.95 would be $1.59.
Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
Answer:
The length of the long side is 147 ft
The length of the short side is 30 ft
Step-by-step explanation:
L=5s-3
s= 324-2L
324=2(5s-3)+s
distribute
324=10s-6+s
simplify
324=11s-6
add 6 to both sides
330=11s
divide by 11
30=s
Plug in the s value to determine the length of the long side
