Answer:
70.8 to one decimal place,
or to be exact : 70.7873
Step-by-step explanation:
In right angle triangles, trigonometry functions can be used
here tan out of sin, cos ,tan seems the most appropriate
tan(x) = opposite/adjacent
tan(x) = 6.6/2.3
x = tan^-1 (6.6/2.3)
x = 70.7873
The improper fraction form of 4 2/3 would be 14/3, if that is one of the choices.
rise over run
(-1,2) (2,2)
2-2/2-(-1)
2-2/2+1 equals 0/3
or alternatively
2-2/-1 - 2 which would be -0/3.
Whichever point is the first helps determine this alot
rise/run=rise over run= y2 - y1/ x2 - x1
Answer:
Step-by-step explanation:
So you can use the special formula for 30-60-90 triangle or you can use the whole Soh Cah Toa thing.
I honestly prefer trig. so a is the opposite side of the 30 deg and 12 is the hyp. This should scream sine to you since sine goes with opposite/hypotenuse.
sin(30 deg)=a/12
Multiply both sides by 12
giving a=12 sin(30)
Type into calculator unless you know your unit circle well.
a=6
Answer: { x | 5 < x ≤ 100 } OR { x ∈ ℝ | 5 < x ≤ 100 }
Step-by-step explanation:
{ x | 5 < x ≤ 100 }
This means:
"The set of all x's, such that x is greater than 5 and less than or equal to 100"
Another acceptable way to write this is
{ x ∈ ℝ | 5 < x ≤ 100 }
"x ∈ ℝ" simply means x is an element of all real numbers
