Answer:
( -
/2 , -1/2)
Step-by-step explanation:
-210 degrees in standard position corresponds to an angle in the 3rd quadrant 30 degrees below the negative x-axis
The hypotenuse of the triangle here is 1, and we want the coordinates.

Answer:
2916 cm
Step-by-step explanation:
In area you have to multiply
So all I did was
18x18x9
which equals 2916
295 she spent
y dollars she can spend on other expanses
then 295+x+y=500
implies x+y=205
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
Answer:
C=13
Step-by-step explanation:
Pythagorean theorem
a^2 + b^2=c^2
a squared plus b squared equals c squared
