Answer:

-(1/2) or -0.5

Step-by-step explanation:

select two coordinates. for example, (2,2) and (4,1).

do (y2 - y1) ÷ (x2 - x1).

in this case, (1 - 2) ÷ (4 - 2). you should end up with -(1/2), or -0.5

trapecia [35]

Answer:

Sum = 2,340°

Step-by-step explanation:

Sum  of interior angles = 180·(n-2),

where n is the number of sides the polygon has

Sum = 180·(15-2)

Sum = 180·13

Proove that <br>1/1-sin theta + 1/1+cos theta = 2×sec square theta ​
Rina8888 [55]

Step-by-step explanation:

We need to prove that,

\dfrac{1}{1-\sin\theta}+\dfrac{1}{1+\sin\theta}=2\times \sec^2\theta

Taking LHS,

\dfrac{1}{1-\sin\theta}+\dfrac{1}{1+\sin\theta}\\\\=\dfrac{(1+\sin\theta)+(1-\sin\theta)}{(1-\sin\theta)(1+\sin\theta)}\\\\=\dfrac{2}{1-\sin^2\theta}\\\\\text{As}\ 1-\sin^2\theta=\cos^2\theta\\\\=\dfrac{2}{\cos^2\theta}\\\\\text{As}\ \dfrac{1}{\cos^2\theta}=\sec^2\theta\\\\=2\sec^2\theta\\\\=RHS

Hence, LHS = RHS.
