Answer:

See below

Step-by-step explanation:

\frac{1}{1-cos A} - \frac{1}{1+cos A} =2 cosec A cot A \\  \\ L. H. S.= \frac{1}{1-cos A} - \frac{1}{1+cos A} \\  \\ = \frac{1+cos A - (1 - cos A)}{(1-cos A)(1+cos A)}\\  \\ = \frac{1+cos A - 1  +  cos A}{1-cos^{2}  A}\\  \\ = \frac{2cos A }{sin^{2}  A}\\  \\ =2 .\frac{1}{sin A}.\frac{cos A }{sin  A}.\\  \\  = 2.cosec \: A.cot \: A \\  \\  = R.H.S

if the line AB with A(-1,5) and B(3,7) is perpendicular to the line CD WITH C(7,11) AND D(X,23). THEN X=?​
MissTica

Answer:

x=1

Step-by-step explanation:

slope AB = (7-5) / (3 - -1) = 2 / 4 = 1/2

slope CD = (23-11) / (x-7) = 12 / (x-7)  

12 / (x-7) = - 2  ... perpendicular to AB slope 1 = - 1/slope 2

-2 (x-7) = 12

-2x + 14 = 12

-2x = -2

x = 1

Explain me step by step plz​
OlgaM077 [116]

Answer:

28

Step-by-step explanation:

We know that the heights and bases of all of the parallelograms will be the same because they are equal, therefore, since the height of 2 parallelograms is 14, the height of one parallelogram is 14 / 2 = 7. Since the areas of all of the parallelograms are congruent, the area of one parallelogram is 308 / 4 = 77. The parallelogram area formula is A = bh where A, b and h are area, base and height respectively and we know both the area and height so we need to solve for b. Doing so we get 77 = b * 7 so that means b = 11. The length of y is two bases + 6 and since we know the base is 11, y = 11 * 2 + 6 = 22 + 6 = 28.
