ΔXYZ ≅ΔFED where m∠X = 50°, m∠Y=30°, m∠D=2y+10, XY =9 and EF=3x−12. Solve for x and y.
Delicious77 [7]

Answer:

The value of x is 7 and value of y is 45

Step-by-step explanation:

In ΔXYZ

∠X = 50°, ∠Y=30°

To Find ∠Z we will use angle sum property of triangle (Sum of all angles of triangles is 180°)

So,∠X + ∠Y + ∠Z = 180°

So,50°+30°+ ∠Z = 180°

∠Z=180°-80°

∠Z=100°

Now we are given that ΔXYZ ≅ΔFED

So, the corresponding sides are equal and the corresponding angles are equal.

So, ∠Z= ∠D

So, 100=2y+10

100-10=2y

90=2y

45=y

Now XY = EF

So, 9 = 3x-12

21=3x

7=x

Hence The value of x is 7 and value of y is 45

Find the perimeter of a rectangle when it’s length is three times it’s width and the area is 108
Natasha2012 [34]

Answer:

Step-by-step explanation:

Let w = width

 

Then 3w = length

 

A= LW

 

108 = (3w)(w)

 

108 = 3w2

 

36 = w2

 

6 = w   18 = length  Perimeter = 2(6) + 2(18) = 48 in

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and
Ugo [173]

The Area of rectangle is "30 \ unit^2" and the equation of the semi circle is "y = \sqrt{36-x^2}".

According to the question,

The vertices of rectangle,

(5, 0) and (-5, 0)

Length,

l = 10 unit

Breadth,

b = 3 unit

Radius of semi circle,

r = 6

Centre of origin,

(0, 0)

As we know,

→ The Area of rectangle is:

= Length\times Breadth

= 10\times 3

= 30 \ unit^2

and,

→ The Equation of semi circle is,

y = \sqrt{r^2-x^2}

by substituting the values, we get

  =\sqrt{(6)^2-x^2}

  = \sqrt{36-x^2}

Thus the above is the correct answers.
