Answer:

Step-by-step explanation:
If the figures are similar, then the angles are the same. So that means that angle H is equal to angle D (you can count he little arcs in the angle to find it's matching partner). Since this is true:

Which is the same as
. Solve for x by dividing both sides by 4:

Finito.
Answer:
6
Step-by-step explanation:
If a restaurant has 3600 to spend on ads which costs 600 each, then they can buy 6 ads.
They can buy 6 ads since 3600/600 = 6.
h = 
multiply both sides by 2 to eliminate the fraction
2A = ( b + c)h
isolate h by dividing both sides by (b + c)
h = 
Yes, one pair of sides is both parallel and congruent
I think that's it
