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:
D
Step-by-step explanation:
A shift of 4 units horizontally left means subtract 4 from the x- coordinate, leaving the y- coordinate unchanged.
A shift of 4 units horizontally right means add 4 to the x- coordinate while leaving the y- coordinate unchanged.
Hence translation rule is
(x, y) → (x - 4, y), that is
(- 4, 6) → (- 4 - 4, 6) → (- 8, 6)
Answer: Graph A and Graph C hope this helps
Step-by-step explanation:
To simplify the fraction, we need to rationalize the denominator by multiplying the numerator and denominator by the conjugate.
The conjugate is the same thing as the denominator with a plus sign instead of a minus sign.
(sqrt(2) + start(5))^2/((sqrt(2) - start(5))(sqrt(2) + start(5)))
FOIL the top and bottom.
The answer is -(7+2sqrt(10))/3
