Put your calculator in <em>degrees mode</em>.
1.45 is the correct number of <em>radians</em>.
Answer:
450L
Step-by-step explanation:
This is a ratio and proportion problem. First you need to determine the known ratio and the unknown ratio. In this case we have the known ratio:
The unknown ratio in this case is:
So to do this, we just set up the proportion and solve for it:
7 > 8
7 + 8 = 15
180 / 15 = 12
12 * 7 = 84
Therefore the smallest angle is 84 degrees
Answer:
D. x. x^7 . x^-4
Step-by-step explanation:
A. X^5 . X^-4 .X^2=X^(5-4+2)= X^3
B. X^-2 .X^9 .x^-4=X^(-2+9-4)= X^3
C.x^0 . x^10 . x^-7=X^(0+10-7)= X^3
D. x. x^7 . x^-4=X^(1+7-4)= X^4
Answer:
x = 3
Step-by-step explanation:
Multiply the first equation by -1, then add it to second equation.
2x+9y = -12
-2x-7y = 8
-------------------
2y = -4
Solve for y
2y = -4
y = -2
Plug value of y into one of the equations and solve for x
2x + 9(-2) = -12
2x = 6
x = 3
