Step-by-step explanation:
Given
perpendicular (p) = a
hypotenuse (h) = 3√2
sin 45 ° = p/h
1 /√2 = a / 3√2
Cross multiply
3√2 = a √2
a = 3√2 / √2
Therefore a = 3.
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
So p(10)=N Means :10;10hours past midnight
X+2y=1
2y =1-x
y= (1-x)/2
5x-4y= -23
By substituting the value of y in this equation
5x -4 {(1-2)/2} = -23
5x- 2 +2x = -23
7x= -21
x= -3
Now, let's find the value of y bu putting the value in any othe two equations
I'll use x +2y=1
-3 +2y=1
2y =4
y=2
So, the value of x and y is -3 and 2 respectively.
Answer: 3
Step-by-step explanation:
Set them equal because they are the same so 15x+5=16x+2 so x+2=5 so x=3
