Answer:

The answers are 54 degrees and 234 degrees

Step-by-step explanation:

mathematically we have the tan positive on only two axes

these are the first (0-90) degrees and the 3rd quadrant (180-270)

We start by find the arc tan of the angle value

Thus;

x = arc tan (1.3562)

x = 54 degrees

On the third quadrant, we have it that;

180 + 54 = 234 degrees

leva [86]

Answer:

x=4

Step-by-step explanation:

first lets move it over

3x = 12

x=4

check:

14*4 = 56

-5 =

7+ 11x=

11*4 = 44

44+7 = 51

51 = 51

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard

galben [10]

Answer: $15r^2-21r+5$

Step-by-step explanation:

Given: Perimeter of triangular garden = $25r^2 - 9r + 14$

The sum of two sides of the garden = $10r^2 + 12r + 9$

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

$=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5$

The expression represent the third side = $15r^2-21r+5$ .

In the sequence 3 8 13 18 what term of the series is the number 2218

77julia77 [94]

By clearly looking at the sequence there are in Arithmetic Progression
So for finding which term is 2218 in that sequence
we have x_{n} = a+ (n-1)d
Here,
a=3
x_{n}=2218 & d=5(by looking at the sequence given)
by substituting those values we get our desired result
2218=3+(n-1)5
2218-3=(n-1)5
2215=(n-1)5
2215/5=n-1
453=n-1
n=454
so 454 term is 2218
