Please help me asap!!!

Answer:

Choice A.......< B is 147 degrees

Step-by-step explanation:

The total sum of the interior angles of a pentagon is 540 degrees

...So let's count the angles that we already have:

<A is 90

<B is ?

<C is 105

<D is 108

<E is 90

Noticed that both angles A and E are 90 since they have that little square that represents a straight angle.

Let's find the value for <B

90+ x + 105 + 108 + 90= 540

                        393 + x= 540

                                   x= 540 -393

                                   x = 147

So angle B is 147 degrees

Step-by-step explanation:

Explanation:

the initial statement is  

y

∝

x

to convert to an equation multiply by k the constant

of variation

⇒

y

=

x

to find k, use the given condition for x and y

y

=

10

when  

x

=

5

y

=

k

x

⇒

k

=

y

x

=
