See the comment above.
Interchange the x and y in the original equation. call f(x) = y just for ease of understanding.
y = 3x + 5
Inverse
x = 3y + 5 Now solve for y.
(x - 5) = 3y Divide by 3
(x - 5)/3 = y

Remove the brackets.
x /3 - 5/3 = y

The answer is D <<<<< answer.

Answer:

The correct option is C ) 109.5°

Therefore,

$m\angle E=109.5\°$

Step-by-step explanation:

Given:

In Triangle DEF

d = 10

e = 18

f = 12

To Find

angle E = ?

Solution:

In Triangle DEF , Cosine Rule says

$\cos E=\dfrac{f^{2}+d^{2}-e^{2}}{2fd}$

Substituting the values we get

$\cos E=\dfrac{12^{2}+10^{2}-18^{2}}{2\times 12\times 10}$

$\cos E=\dfrac{-80}{240}=-\dfrac{1}{3}$

Therefore,

$\angle E=\cos^{-1}(-0.3333)$

$m\angle E=109.5\°$ ............As it is in Second Quadrant

Therefore,

$m\angle E=109.5\°$
