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
Hopes this if it doesn’t I any so sorry if I got it wrong:

Step-by-step explanation:
<u>Linear approximation formula</u>

Given function:




Use the chain rule to differentiate the function.

Differentiate the two parts separately:


Put everything back into the chain rule formula:

.
The <u>linear approximation</u> at a = 8 is:

Finally, substitute x = 7.8 into the <u>linear approximation equation</u>:
