Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) = 
cos(40) = 
0.766 ≈ 
3.06 ≈ x
x ≈ 3.06
Answer:
w = -12
Step-by-step explanation:
w/6 + 5/8 = -1 3/8
Subtract 5/8 from each side
w/6 + 5/8-5/8 = -1 3/8 - 5/8
w/6 = -1 3/5 - 5/8
w/6 = -1 8/8
w/6 = -2
Multiply by 6 on each side
w/6 *6 = -2*6
w = -12
Turns out that both of these numbers are PRIME! Neither of them can be divided down with the same number or different. Hope this helps!
You will have to use the SAS postulate :))
If you are solving for the question in the picture your answer would be 18. Whiich is letter A.
12x+15y=390 Original Equation
12(10)+15y=390 Replace x with 10
120 + 15y= 390 Mutiply 12 by 10
-120 = -120 subtract 120 on both sides to simplfy the equation
15y= 270 New equation
÷15 = ÷15 To get the variable alone divide 15 on both sides
y=18 Your value for y.
