Answer:
We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.
Step-by-step explanation:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a.
Answer: x=-2
Step-by-step explanation:
First subtract 4 from both sides
Sqrt(x+3)=1
Then square both sides
X+3=1
Then subtract 3
X=-2

Answer:
Never true
Step-by-step explanation:
2x - 5 < 2(x - 3) first multiply 2 with the inside the parenthesis
2x - 5 < 2x - 6
now when we simplify the inequality 2x on the both sides will be eliminated and we will be left with:
(-5) < (-6) which cannot be true because (-5) is closer to 0 in number line so it's bigger then (-6) not smaller
Therefore the answer is "Never true"
