Answer:
(2A /h) - b1 = b2
Step-by-step explanation:
A = 1/2 h ( b1 + b2)
Multiply each side by 2
2A = 2*1/2 h ( b1 + b2)
2A = h ( b1 + b2)
Divide each side by h
2A/h= h/h ( b1 + b2)
2A/h= b1 + b2
Subtract b1 from each side
2A /h - b1 = b2
(i): A triangle where all three sides are equal and the same.
(ii): A triangle where all three sides are unequal in length.
(iii): A triangle that has two sides of equal length.
(iv): A triangle where all three internal angles are acute(they measure less than 90 degrees.
(v): A triangle where all three internal angles are obtuse(measure above 90 degrees).
(vi): A triangle where one internal angle is a right angle(90 degrees).
Hope this helps

Answer:
Scale factor = 
Perimeter ratio = 4 : 9
Surface area ratio = 16 : 81
Volume ratio = 64 : 729
Step-by-step explanation:
Volume ratio = 
= 
=
= 64 : 729
Scale factor = ![\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B%5Ctext%7Bvolume%20of%20small%20prism%7D%7D%7B%5Ctext%7BVolume%20of%20large%20prism%7D%7D%7D)
= ![\sqrt[3]{\frac{64}{729}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B64%7D%7B729%7D%7D)
= 
Perimeter ratio = Scale factor
= 
= 4 : 9
Surface area ratio = (Scale factor)²
= 
= 
= 16 : 81
