Find the value of x and the value of y

B. y = 4 root under 2, x = 7

B. is the correct answer.

Step-by-step explanation:

I drew AB such that it is equal and parallel to CD and perpendicular to ED. So, ABCD is a rectangle.

now

triangle ABE is a right angled triangle so

taking 45 as reference angle,

sin45 = p/h

or, sin45 = AB/AE

or, sin45 = 4/y (AB = CD = 4)

or,y = = 4/sin45

now

ABCD is a rectangle

BD = AC = 3

in triangle ABE

AB = 4

using pythagoras theorem

h² = p²+b²

or, y² = AB²+ EB²

or,

or, 32 = 16 + EB²

EB² = 16

so, EB = 4

Now

x = EB+BD

= 4+3

so, x = 7

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
