Answer:
Step-by-step explanation:
Given
Required
The measure of each angle
First, we calculate the length of the three sides of the triangle.
This is calculated using distance formula
For AB
So:
For BC
For AC
So, we have:
By representation
So, we have:
By cosine laws, the angles are calculated using:
Collect like terms
Solve for
Take arc cos of both sides
Collect like terms
Solve for
Take arc cos of both sides
For the third angle, we use:
--- angles in a triangle
Make C the subject
First you have to make both fractions have the same denominator, so you can multiply each fraction by the others denominator.
5/8
To
(5*6)/(8*6)
And
1/6
To
(1*8)/(6*8)
Now it's 6 30/48 - 2 8/48
= 4 22/48
Now reduce to
= 4 11/24
So, 4 11/24 is the answer
You can see that you're constantly subtracting 8 to get the next number. So, we have
So, as you can see, to get the n-th term we must subtract (n-1) times 8 from the original number.

Answer:(0,3)Step-by-step explanation:The solution in a set of graphs is where they intersect. In this graph, they intersect at (0,3)
Answer:
B 244
Step-by-step explanation:
6^3 +7*4
PEMDAS says exponents first
216 + 7*4
Then multiply and divide
216 +28
Now we add and subtract
