Answer:
A= (b1+b2)/2 then multiplied by h.
h=2(A/b1+b2)
height is 6 centimeters
Step-by-step explanation:
For area formula, you would add the bases, divide by 2, then multiply by height
For height formula, you would divide the area by the sum of base one and two, then multiply by two. Using that formula, it would be 72/(16+8) which equals 3, then multiply by 2, equaling 6.

Answer:
a = 12 b = -4
Step-by-step explanation:
To solve this equation it would be easiest to use the elimination method
a + b = 8
a - b = 4
a = 12
Now all we have to do is substitute 12 for a in any equation. For this I will use the first one.
12 + b = 8
Lastly subtract 12 from both sides
b = -4
All are congruent. Congruent means identical in size or shape. the different markings on the two shapes show that they are congruent. I can’t fully see number 10 so I can’t say it that one is or not
