Answer:
No, the triangles are not similar
Step-by-step explanation:
The (reduced) side length ratios, shortest to longest, are ...
12 : 18 : 20 = 6 : 9 : 10
and
5 : 12 : 13
These are not the same, so the triangles are not similar.

<h3>Quadratic functions</h3>
Quadratic functions are functions that has a leading degree of 2.
Given the equation that represents roller coaster’s height as shown
h = –0.025t^2 + 4t + 50
The coaster will reach the ground when h = 0
Substitute
0 = –0.025t^2 + 4t + 50
Factorize
On factorizing, the time it took the rider to reach the ground level is 171.651seconds
