Question

What is the value of a? 6/298V 36v2​

Answer 1

Step-by-step explanation:

a= the height of the triangle=h

$h^{2} = ef$

by ef, e= 18 & f=4

so...

$h^{2} = 18 \times 4 = 72$

so you put both of them in a square root

$\sqrt{h} = \sqrt{72}$

so the answer will be

$h = \sqrt{72} = 6 \sqrt{2}$
