Pleaseee helppppppppppppppppppp

To find Angle A we use cosine

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is 17

The hypotenuse is 38

So we have

cos A = 17/38

A = cos-¹ 17/38

A = 63.4

<h3>A = 63° to the nearest degree</h3>

To find Angle C we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 17

The hypotenuse is 38

So we have

sin C = 17/38

C = sin-¹ 17/38

C = 26.57

<h3>C = 27° to the nearest degree</h3>

Hope this helps you

The number of hours a typical student spends per week at school has an Order of Magnitude of 1.
Margarita [4]
If the number of hours in school each week is somewhere between 20 and 40, then it can be written in scientific notation as
  2.0×10¹ to 4.0×10¹

The exponent of 10 in each case is 1, so we can say the Order of Magnitude is 1.
  TRUE


_____
In Engineering terms, the order of magnitude is sometimes considered to be the integer part of the base-10 logarithm of the number.
  log(20) ≈ 1.3010
  log(40) ≈ 1.6021
If we round these numbers to integers, we find the order of magnitude of the first is 1; the order of magnitude of the second is 2. Thus a student who spends 6 hours per day for 5 weekdays in class will have hours with an order of magnitude of 1, while a student who spends 7 hours per day for 5 days each week will have hours with an order of magnitude of 2. This question is best answered by considering "order of magnitude" in the simplistic terms of the answer above: the exponent of 10 in scientific notation.

select the irrational number? A)√9 B)√12 C)√16 D)√20 E)√25 (there should be more than one answer)
GenaCL600 [577]
The answers are:
__________________________
    [B]:  "√12 " ;   AND:
__________________________
    [D]:  "<span>√20" .
__________________________
Note:  "Irrational numbers" have decimals that are:  1) non-terminating;  AND:  2) non-repeating.
__________________________
Consider the answer choices given; and consider the given information that there "should be no more than one answer.
__________________________________
Consider the following answer choices:
__________________________________
Choice A)  "</span><span>√9"  =  3 .  Rule out this choice.
__________________________________
Choice C)  "</span><span>√16" = 4 .  Rule out this choice.
__________________________________
Choice E)  "</span><span>√25" = 5.   Rule out this choice.
_________________________________
We are left with 2 (two) remaining answer choices:
    [B]:  "</span>√12"  ;  and:  [D]:  "<span>√20" .
_________________________________
If there are more than one answer, then these two choices should be the correct answer.   However, let us explore these two choices, using a calculator.
____________________________
    [B]:  </span>"√12"  =  3.4641016151377546

    [D]:  "√20"  =  4.4721359549995794
_________________________________
These two answer choices should the correct answers.
