The relation between arc length and exterior angle is given in the figure.
Now we are given far arc length as DE =124
We are given near arc length as BC = 36
So plugging in the formula to find measure of angle A:
Angle A = 44 degrees
Answer : A) 44 degree
Answer:
Step-by-step explanation: una roca se unde porque aunq tiene una forma solida igualmente que un barco, la roca no tiene aire dentro de ella, a diferencia del barco que es hueco por dentro, contiene aire causando que flote y no pueda hundirse
f(x) - g(x)
=> (3x² + x - 3) - (x² - 5x + 1)
=> 3x² + x - 3 - x² + 5x - 1
=> 3x² - x² + x + 5x - 3 - 1
=> 2x² + 6x - 4
Answer:

Answer:
The perfect -square trinomial
(9y+7)²
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomial equation
81 y² + 126 y +49
⇒ 9² y² + 2(9)(7)y + 7²
⇒ (9y)² + 2(9)(7)y +7²
we will use formula
(a+b)² = a² + 2ab +b²
⇒ (9y+7)²
<u><em>Final answer:-</em></u>
The perfect -square trinomial
(9y+7)²
