Answer:

The side lengths are:

15, 30, and 30

Step-by-step explanation:

Let x determine the length of the smallest side length then

the other one is said to be 15 in larger so it's x + 15

finally the third size is said to be twice as the smallest one so it's 2x

The perimeter is the sum of all three sides added up

x + 2x + x + 15 = 75 add like terms

4x + 15 = 75 subtract 15 from both sides

4x = 60 divide both sides by 4

x = 15

natita [175]

Answer:

given,

selling price (sp)=rs 5 ×30

=rs 150

now, gain %=20%

cost price (cp)=

$\frac{sp \times 100}{100 + gain\%}$

$= \frac{150 \times 100}{100 + 20}$

therefore cp= rs125

now,

again in 2nd case

sp= rs 27×5

therefore sp=rs 135

and cp= rs125

now, sp>cp so,

$gain\% = \frac{sp - cp}{cp} \times 100\%$

or, gain=

$= \frac{135 - 125}{125} \times 100\%$

therefore gain %= 8%.... is answer

hope it helps..

Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

= $2\sqrt{sin^{2}x }$ * cosx

= $2\sqrt{(1-cos^{2}x }$ * cosx

= 2 $\sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}$

= $\frac{8}{5} * \frac{3}{5}$

= 24/25
