Variables are used in algebra and other branches of mathematis.
They are represented by letters. Usually ( but not necesserally) the letters at the end of the alphabet like x,y and z.
Answer:
option b 5√2
option a 20
option c 4
option d 3/4
option b 3
Step-by-step explanation:
To solve all these questions we will use trigonometry identity which says that
sinΔ = opposite / hypotenuse
1)
sin45 = 5 / KL
Kl = 
KL = 5√2
2)
TanФ = opp / adj
Ф = Tan^-1(5/14)
Ф = 19.65
≈ 20
3)
sin(30) = rq / 8
rq = sin(30)(8)
rq = 4
4)
tan(Ф) = 6/8
5)
angle 3

Answer:
x=0.3
Step-by-step explanation:
Let's solve your equation step-by-step.
3.7(−83x−3)=3.7(7x−30)
Step 1: Simplify both sides of the equation.
3.7(−83x−3)=3.7(7x−30)
(3.7)(−83x)+(3.7)(−3)=(3.7)(7x)+(3.7)(−30)(Distribute)
−307.1x+−11.1=25.9x+−111
−307.1x−11.1=25.9x−111
Step 2: Subtract 25.9x from both sides.
−307.1x−11.1−25.9x=25.9x−111−25.9x
−333x−11.1=−111
Step 3: Add 11.1 to both sides.
−333x−11.1+11.1=−111+11.1
−333x=−99.9
Step 4: Divide both sides by -333.
−333x
−333
=
−99.9
−333
x=0.3
