Who can help me out with this question???

GaryK [48]

Answer:

x = 13

Step-by-step explanation:

$a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\$

Take the square root of both sides

$\sqrt{169} = \sqrt{c^2} \\13 = c$

In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f

White raven [17]

Answer:

$F = 9.75cm$

Step-by-step explanation:

Given

In ABC;

$C = 3.9cm$

$Dilation = 2.5$

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

$F = Dilation * C$

$F = 2.5 * 3.9cm$

$F = 9.75cm$
