Answer: x=1
Step-by-step explanation:
1/2+3/2=2^x
4/2=2^x
2=2^x
x=1
94 if your using the whole frame the math is 5×7=35 we have 2 sides do times 35 by 2 35×2=70 then we do 1×7=7 for the outside of the game then do 7 times 2 b/c you have 2 sides the do your final side by doing 5×1=5 then times that by 2 and you get 10 .70+14+10=94

Answer:
![\cos (115\degree)=-0.423](https://tex.z-dn.net/?f=%5Ccos%20%28115%5Cdegree%29%3D-0.423)
Step-by-step explanation:
The parametric equations of a circle is
and ![y=r\sin \theta](https://tex.z-dn.net/?f=y%3Dr%5Csin%20%5Ctheta)
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and ![y=\sin \theta](https://tex.z-dn.net/?f=y%3D%5Csin%20%5Ctheta)
where
is the angle in standard position,
From the question, the given angle in standard position is
.
This angle intersects the unit circle at ![x=-0.423](https://tex.z-dn.net/?f=x%3D-0.423)
But ![x=\cos \theta](https://tex.z-dn.net/?f=x%3D%5Ccos%20%5Ctheta)
We substitute
and ![x=-0.423](https://tex.z-dn.net/?f=x%3D-0.423)
This implies that: ![\cos (115\degree)=-0.423](https://tex.z-dn.net/?f=%5Ccos%20%28115%5Cdegree%29%3D-0.423)
