Draw and label a standard Oblique Triangle, as we’ve done in our previous lessons.
Determine the given congruence, either SAS or SSS, and pick the equation that helps you solve for either a missing side or angle.
Plug into your chosen equation and solve.
The "Law of Cosines" can be used to calculate one side of a triangle when the angle opposite and the other two sides are known. The "Law of Cosines" can be expressed as c2 = a2 + b2 - 2 a b cos C (1)
The cosine rule is an extension of this mathematic principal that makes it effective for non-right triangles and states that in regard to a certain angle, the square of the side of the triangle opposite that angle is equal to the squares of the other two sides added together, minus two times both..
If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.
What is width?
The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.
How to calculate time?
We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:
It will be as 14/12* 1 hour
=14/12
=1.167
=1.17 hour
Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.
Answer:
y = -12
Step-by-step explanation:
You first calculate the x coordinate using the equation x =
, which in this case is
.
Then plug that x value into the equation to get the y coordinate:
4(-1)²+8(-1)-8 = -12
618+5400=6018
6018+(50+2500)=8568
8568-(47+2900)=5621

Answer:
That smile tho lol
anywayssssss
b= 16 mm
Step-by-step explanation:
Pythagorean theorem is a^2 + b^2= c^2, so-
12^2 +b^2= 20^2
144+b^2=400
b^2=400-144
b^2= 256
b= 16
