Answer:
(0,-2)
Step-by-step explanation:
First of all it is useful to say the notation in a triangle:
Opposite at the side a the angle is called A,
Opposite at the side b the angle is called B,
Opposite at the side c the angle is called C.
So, the Sinus Law can be written:
asinA=bsinB=csinC.
This Law is useful in all the cases SSA and NOT in the case SAS, in which the Law of Cosinus has to be used.
E.G.: we know a,b,A, then:
sinB=sinA⋅ba and so B is known;
C=180°−A−B and so C is known;
c=sinCsinB⋅b
If this is not to professional I don't know what this I'm in 9th grade and kinda have been exposed to this in books
4^2 and 2^4
Btw ^number is the small number
Answer: x < 3
Step-by-step explanation:
Let's solve your inequality step-by-step.
7x−9<12
Step 1: Add 9 to both sides.
7x−9+9<12+9 =7x<21
Step 2: Divide both sides by 7.
7x/7 < 21/7
Answer: x < 3
Answer:
50
Step-by-step explanation:
when you plug in all the values for x, the only one that does not make the inequality true is 50.
