Answer:
(2x^2+5) x (x-2)
Step-by-step explanation:
Answer:
Therefore 'x' is equal to 65.4°
Step-by-step explanation:
In Right Angle Triangle ABC
∠ B = 90°
AC = Hypotenuse = 12
CB = Adjacent Side = 5
To Find:
∠ C = x
Solution:
In Right Angle Triangle ABC Cosine Identity we have

Substituting the values we get


Therefore 'x' is equal to 65.4°
Answer:
I'm pretty sure he or she are right^^idk
Step-by-step explanation:
Answer:
A = 27π units²
Step-by-step explanation:
Note that a central angle of 120 degrees corresponds to 1/3 of a full circle.
The area of the full circle is A = πr², or A = π(9 units)² = 81π units², and so
the area of the sector in question is 1/3 of that, or A = 27π units²
2 I believe I’m not 100% sure tho
