Answer:
The two numbers are 40, and 27.
Explanation:
Since there are only two numbers, with two different aspects, you can just make
a system, and solve.
A sum of two numbers adding up to 67 can be modeled by: x + y = 67.
A difference of those same two numbers being 13 can be modeled by: x – y = 13.
You can add the two equations together to eliminate the y value because the -y and y will cancel out:
x + y = 67.
+ x – y = 13.
And you get: 2x = 80.
Now to find x, just divide by 2 on both sides to cancel out the coefficient of 2 in 2x:
2x = 80
÷2 ÷2
x = 40.
So the first number is 40.
Since we know the first number, we can immediately find the other number by substituting it into the first equation.
x = 40 → x + y = 67
(40) + y = 67
-40. -40
Subtract from both sides to cancel the constant terms.
Then you will get that y or the second number is y = 27.
This is true because 40 + 27 = 67, and 40 - 27 = 13.
Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.
Call that angle C.
Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.
Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees
So each of the 2 equal angles shown has the measure 25.21 degrees.
Unfortunately, I don't know the direction we should go from this point on.
Answer:
only D
Step-by-step explanation:
I am not sure if what I am about to explain is correct but I hope it is somewhere along the correct path
To solve the problem use the following steps below....
Step 1: Take your numbers and place them in parentheses
(4-1/6)
Step 2: Turn your whole number,4, into a fraction
6/6=1
6/6x4=24/6
Step 3: Place your new fraction back into the problem
(24/6-1/6)
Step 4: Use the operation,subtraction, and minus 1/6 from 24/6
(23/6)
24/6 minus 1/6=23/6
Step 5(is optional): Turn 23/6 into a mixed fraction by dividing 23 by 6
23<span>÷6= 3 5/6
Step 6(is optional): put your answer into a final statement
(4-1/6)=23/6=3 5/6
Answer: 3 5/6
I hope this helps and I apologize in advance if any false information was given.
