That's easy, here let me show you a example:
The formula for the area of a trapezoid is:
A= (a+b)/2*h
A=150
h=10
b=14
a=?
So we need to solve for a. Let's plug in the values that we do know...
A= (a+b)/2*h
150=(a+14)/2*10
150=(a/2+14/2)*10
150=(a/2+7)*10
Divide both sides by 10
15=a/2+7
subtract 7 from both sides
8=a/2
multiply both sides by 2
16=a
The other base is 16
Answer:
y = 15
Step-by-step explanation:
Subtract 3 from 18
18 - 3 = 15
It is congruent because congruent means everything is equal or same size
