Answer:

Step-by-step explanation:

Let the breadth = x cm

Length = 2x

2x *x = 18

     x² = 18/2

     x² =9

     x = √9

x = 3 cm

Breadth = 3 cm

Length = 2*3 = 6 cm

Perimeter = 2*(length + breadth)

 =2*(3+6)

= 2*9

Perimeter = 18 cm

Right triangles are triangles with a measure of 90 degrees

The value of x is 76/11

The equation is given as:

sin (3x+5) = cos (8x+9)

To solve for x, we make use of the following theorem

If sin(A) = cos(B), then

A + b = 90

So, we have:

3x + 5 + 8x + 9 = 90

Collect like terms

3x + 8x = 90 - 5 - 9

Evaluate the like terms

11x = 76

Divide both sides by 11

x = 76/11

Hence, the value of x is 76/11

The value of x in the given parallelogram is: x = 7.

A parallelogram has two congruent diagonals that bisect each other into equal segments.

Thus:

KU = Um

Substitute

3x + 3 = 4x - 4

Combine like terms

3x - 4x = -3 - 4

-x = -7

x = 7

Therefore, the value of x in the given parallelogram is: x = 7.

Let's turn each mixed fraction into an improper fraction.

Answer:

1.378 approximately 1.38

Step-by-step explanation:

we're looking for x which is the opposite in the diagram we've been given the hypotenuse in the question as 1.8

so we use sin = opp/hypotenuse

sin50= x/1.8

x = sin50× 1.8

x= 1.378

Answer:

There are two ways to do this problem algebraically or trigonometrically.

Algebraically/geometrically

The ratios of the sides of a 30/60/90 tri. are x, x√3, 2x (short leg, long leg, hyp). Therefore, if the long leg is 6 'units'. then 6 = x√3. x = 6√3.

The hyp is 2x then the hypotenuse is 2(6√3) = 12√3, rationalizing is 12√3/3 = 4√3

Using Trig.

We can use sinx = y/r = opp/hyp. The long leg of 6 is opposite 60 degrees (pi/3).

Therefore, sin(pi/3) = 6/r =

r = 6/sin(pi/3) = 6/(√3/2) = 12/√3, when you rationalize you get 12√3/3 = 4√3

The sine and cosine ratios for a 30°–60°–90° triangle with a hypotenuse of 6, when θ = 60° are  6√3 and 4√3.

This is defined as the longest side of a right-angled triangle and is opposite to the right angle.

The ratios of the sides of a 30/60/90 triangle are x, x√3, 2x (short leg, long leg, hyp). We can infer that the long leg is 6 'units' which is

6 = x√3

x = 6√3.

The hypotenuse is 2x then the hypotenuse is 2(6√3)

= 12√3 when rationalized

= 12√3/3 = 4√3.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The coordinates of the point Q are (25,13).

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Let the coordinates of the point Q be represented by Q(a,b).

Given the Ratio from P to Q is 2:3.

The internal division of the line segment using the ratios will be,

PR/RQ = 2/3

3P = 2Q

3(-10, 3) = 2(a, b)

Now, the coordinates of R can be rewritten as,

[tex]R = (\dfrac{-30+2a}{2+3},\ \dfrac{9+2b}{2+3}) = (4,7)[/tex]

Comparing the coordinates,

(-30+2a)/(2+3) = 4

a = 25

(9+2b)/(2+3) = 7

b = 13
