Answer:
To solve a triangle is to find the lengths of each of its sides and all its angles. The sine rule is used when we are given either a) two angles and one side, or b) two sides and a non-included angle. The cosine rule is used when we are given either a) three sides or b) two sides and the included angle.
Step-by-step explanation:
We just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c2 = a2 + b2 − 2ab cos(C) formula). It can be in either of these forms:
cos(C) = a2 + b2 − c22ab
cos(A) = b2 + c2 − a22bc
cos(B) = c2 + a2 − b22ca

Answer:
Step-by-step explanation:
Given
Required
Find one possible value of x
From the given parameters;
is a possible solution of where y= 7
Substitute 7 for y
Add 3 to both sides
Divide both sides by 2
The result of the inequality implies that x is less than 5; So, the possible values of x is all real numbers less than 5;
Having said that;
is one possible coordinate of
