the perimeter of a triangle is 59 in. The longest side is 11in. longer than the medium side, and the medium side is 3in longer t

Nataly_w [17]

Let the length of shortest side be - x
length of medium side - x +3
length of longest side - x +3 + 11
so , according to question
=> x + x +3 + x +3 + 11 = 59
=> x + x +x + 3 + 3 + 11 = 59
=> 3x = 59 - 17
=> 3 x = 42
=> x = 42/3
=> x = 14
Shortest side = x = 14
medium side = x + 3 = 14+3 = 17
longest side = x + 3 +11 = 14 + 3 + 11 = 28

The side of the parallelogram in the figure above are given in cm.

GrogVix [38]

solution

or, 2 x + y = 5 y - 8 being opposite side of

parallelogram

or , 2x =5 y - y - 8

or, 2x = 4 y - 8

or, x = 4y - 8/2

or,. x = 2y- 4

therefore, 2x + y is equal to 5 y - 8 Being the opposite side of a parallelogram

now,

3y + 2 x is equal to 4x - 3 being opposite side of a parallelogram

or, 3y + 2 x-4x = -3

or,. 3y -2x = -3

What is the sine cosine and tangent of 360 degrees

Mrac [35]

Sine and cosine has period of 2π and tangent has period of π

So basically same question as sin(0), cos(0), and tan(0)

sin(0) = 0

cos(0) = 1

tan(0) = sin(0) / cos(0) = 0 / 1 = 0

So final answers are sin(360°) = 0, cos(360°) = 1, tan(360°) = 0
