All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.
a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
Answer: C
Step-by-step explanation: When triangles are similar, all of their angles should be equal to their respective angles on the other triangle.
Noed of them because it would have to end in two zeros
