Step-by-step explanation:
Co terminal angles are angle ± 2π, that is
+ 2π
= + 
= 
and
- 2π
= - = - 
The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3) Then distribute the multiplication through the parentheses.
-x+1=2x+6 Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3
Answer:
x = 10
Step-by-step explanation:
a² + b² = c²
6² + 8² = c²
36 + 64 = 100
√100 = ±10
x = 10
Answer:
See below.
Step-by-step explanation:
52 as there is a total of 52 in the pack.
Probability (drawing a red card) =26/52 = 1/2.
4 aces.
Probability(drawing an ace) = 4/52 = 1/13.
Probability(drawing a numbered card) = 40/52 = 10/13.
