Given:
The four expression in the options.
To find:
Which expression is equal to –1.
Solution:
In option A,
In option B,
In option C,
![[\because \sin(\pi+\theta)=-\sin \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%28%5Cpi%2B%5Ctheta%29%3D-%5Csin%20%5Ctheta%5D)
In option D,
![[\because \tan(\pi+\theta)=\tan \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctan%28%5Cpi%2B%5Ctheta%29%3D%5Ctan%20%5Ctheta%5D)
Therefore, the correct option is C.
Answer:
17
Explanation:
(x + 8) + (8x + 1) = 90
Combine like terms to get:
9x + 9 = 90
Subtract 9 on both sides:
9x = 81
Divide by 9:
x = 9
Plug in 9 for x in
9 + 8 = ?
9 + 8 = 17
Answer:
<h2>200 is. the answer and if u get it wrong its not my problem im just tryna get some points</h2>
First, find the area of the circle
pie*radius to the power of 2(radius*raduis)
(11*11=121) 121*3.14=379.94
take your answer and divide it by 4 we would divide it by 2 if we had a semicircle but since we have a 3/4 circle we divide by 4 and then times the Quotient by 3
379.94/4=94.985
94.985*3=284.955
Round ur answer to the nearest tenth so it equals 284.96
