Answer:
$0.75
Step-by-step explanation:
6 divided by 8
It's not valid because there are too many unknown quantities, meaning there is not exactly one triangle that could exist for any given SSA combination.
For a visual example, see the attached image below.
It's fairly obvious that 
. One is acute, the other is obtuse. In the triangle on the right, the dashed side has the same length 
as in the triangle on the left. This dashed side and the actual side form an isosceles triangle with congruent base angles 
. The angles 
and are supplementary (they add to 180 degrees), or 
.
Now by the law of sines, in the first triangle,
and that in the second triangle,
but we also know that 
. Hence 
.
Two different angles in this arrangement allow for two different triangles to be constructed, so having a SSA correspondence between two triangles is not enough evidence for their congruence.
A) x² + y² = 327
B) x * y = 101
Solving equation B for y²
B) y² = 10,201 / x²
Substituting this into equation A)
x² + 10,201 / x² = 327
x^4 + 10,201 = 327x²
x^4 -327x² + 10,201 = 0
Using the quartic equation calculator: http://www.1728.org/quartic.htm
x1 = 17.090169943749476
x2 = 5.909830056250525
x1 * x2 = 101
x1 + x2 = 23
Answer:
13/14 > 25/28
Step-by-step explanation:
Answer:
66
Step-by-step explanation:
One way of solving this is to first add 12 to get the number to 0. Then add another 54 to get to 54 degrees. Then you can add these two numbers together to get 66.
