hey there!!
Given :
f ( x ) = l 2x - 4 l , find f ( - 7 )
We will have to substitute the value of -7 instead of x
f ( -7 ) = l -14 - 4 l
f ( -7 ) = l -18 l
As the value in a mod shall always be positive, the answer would become 18
Hence, the required answer is 18
Hope my answer helps!!
Is it 1 or 3 questions ??
Answer:
ABCD has four congruent angles.
Step-by-step explanation:
Solution:
The given statement is :Two supplementary angles are congruent.
Two angles are said to be supplementary if sum of these two angles is 180°.
Let one Angle be A, then another angle will be 180 - A.
As given:
A≅180-A
A=180 -A
A +A= 180
2 A = 180
Dividing both sides by 2, we get
A= 90°
The Measure of each angle will be of 90°.
i.e , d = 90°
