The answer is A. Please let me know if i'm wrong
Answer:
A
Step-by-step explanation:
Given
f(x) = 
let f(x) = y and rearrange making x the subject
y =
( multiply both sides by 4 )
4y = x + 3 ( subtract 3 from both sides )
4y - 3 = x
Change y back into terms of x
(x) = 4x - 3 → A
Step-by-step explanation:
Let,





Therefore,
The number = 135
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
The answer is the triangles could have the same shape( that is all the angles are equal) but the sides may not be the same length . Thay are similar but not necessarily congruent.
C is the correct choice.
