What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the so

wel

Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

$/hyp/^{2}$ = $/adj1/^{2}$ + $/adj2/^{2}$

$/DE/^{2}$ = $/EF/^{2}$ + $/DF/^{2}$

$/16.2/^{2}$ = $/EF/^{2}$ + $/13.6/^{2}$

262.44 = $/EF/^{2}$ + 184.96

$/EF/^{2}$ = 262.44 - 184.96

= 77.48

EF = $\sqrt{77.48}$

= 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.

Hi there! :)

Answer:

$\huge\boxed{v = -27}$

$\frac{v-3}{4} = \frac{9+2v}{6}$

Cross multiply:

$6 ( v - 3) = 4 ( 9 + 2v)$

Distribute:

$6v - 18 = 36 + 8v$

Isolate the "v" variable:

$6v - 18 + 18 = 36 + 18 + 8v$

$6v = 54+ 8v$

$6v - 8v = 54+ 8v - 8v$

$-2v = 54\\\\v = -27$
