Answer:
x=40
Step-by-step explanation:
x= 360-(273+47)
Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
A circle with a radius of 4cm sits inside a circle with a radius of 11cm
What is the area of the shaded region?

Answer:
- (C)The common ratio is –2.0
Step-by-step explanation:
<u>Given sequence:
</u>
This is not AP as the difference in terms is not common
<u>This is GP with the common ratio of -2 as:</u>
- -19.2/9.6 = 9.6/ -4/8 = -4.8/2.4 = -2
Correct choice is (C)
