Answer:
∠ A = 72°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
∠ ECD = 180° - (90 + 54)° = 180° - 144° = 36°
∠ ACB = ∠ ECD = 36° ( vertical angles )
Since AC and BC are congruent then Δ ABC is isosceles, thus the base angles are congruent, that is
∠ A = ∠ B
∠ A = = = 72°
Wait, what graph? Are you answering a question? I dont really understand what you're saying...
First distribute 2a+8-2a-8
The answer is 0
Step-by-step explanation:
Hi Friend !!!
Here is ur answer !!!
(x-1)(x+1)(x²+1)(x^4 + 1)
= (x²-1)(x²+1)(x^4 + 1)
=( x^4 -1)(x^4 + 1)
=( x^8 -1)
The whole is with the help of (a-b) (a+b) = a²-b²
Hope it helps u :-)
