Answer:

Cos x

Step-by-step explanation:

HINT:

1 -   Sin² x = Cos² x

Sec x = \frac{1}{Cos x}

Sec x - Sec x*(Sin x)² = Sec x (1 - Sin² x)

                                  = Sec x * Cos²x

                                  = \frac{1}{Cos x}*Cos^{2} x

                                  = Cos x

9y-5x=20 i dono how to do this x and y intercwpt thingy
bagirrra123 [75]
     9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9

Line segment ab has endpoints a(9, 3) and b(2, 6). find the coordinates of the point that divides the line segment directed from
Dominik [7]
When we are to divide the line segment such that the ratio is 1:2, there are actually 3 parts of the segment. First, we determine the distance between the coordinates and divide the distance by 3. Then, we add the quotient to the x-coordinate.

x-coordinate:    (2 - 9) / 3 = -7/3
y-coordinate:    (6 - 3 ) / 3 = 1

Adding them to the coordinates of a,
           x - coordinate: (9 - 7/3) = 20/3
           y - coordinate: (3 + 1) = 4
Thus, the coordinates are (20/3, 4).

Gala2k [10]

Answer:

  29°, 58°, and 93°

Step-by-step explanation:

If the angles opposite are equal, the sides are equal. In order to have three different side lengths, you must have <em>three different angles</em>.

a farmer has one square mile of land if he divides his land into square fields that are half mile long and half my wife how many
jok3333 [9.3K]
He would have four fields. Since the area of 1/2 milex1/2 mile is 1/4, and 1x1 is 1, so 4 fields make up the land.
