Lisa [10]

Step-by-step explanation:

2 right triangles are formed.

x is the angle btw wire and grnd

tan x = 10/5 = 2

tanx = ht of tower/(5+14)

2 = tower ht/19

tower ht = 38

length of wire =

$\sqrt{ {38}^{2} + {19}^{2} }$

F(c)= 9/5c+ 32 I just don't understand how to find the inverse of the function

Viefleur [7K]

F = 9/5 C + 32
- 32 -32

subtracting - 32 from both sides

F - 32 = 9/5c
5/9 F -32 = 5/9(9/5)C

Invert 9/5 to 5/9 multiply to both sides

5/9F - 32 = C

The answer is 5/9F-32 = 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

$F = Dilation * C$

$F = 2.5 * 3.9cm$

$F = 9.75cm$
