Answer:

Below.

Step-by-step explanation:

SinA×tanA/1-CosA

As tanA = sinA / cos A we have

sin^2A / cosA(1 - cosA)

= (1 - cos^2A) / cosA(1 - cosA)

= (1 - cosA)(1 + cosA) / cosA(1 - cosA)

= (1 + cosA) /cos A

= 1 + 1/cosA

= 1 + secA.

what is the common number to be subtracted from each term of the ratio 11:8 to get the new ratio 2:1.?

JulijaS [17]

Answer:

5 should be subtracted from each term

Step-by-step explanation:

$\frac{11-x}{8-x}=\frac{2}{1}$

Cross multiply,

1 * (11 - x) = 2*(8-x)

11 -x = 2*8 - 2*x

11 - x = 16 - 2x

Subtract 11 from both sides,

-x = 16 - 2x - 11

-x = 5 - 2x

Add 2x to both sides

-x +2x = 5 - 2 + 2x

x = 5

The figure shown has a parallelogram on top and a rectangle below it:

Verdich [7]

Area of a parallelogram = b×h
= 13.4×48.2
= 645.88 inches square
Area of rectangle = l×b
=7.3×48.2
= 351.86
Area of the figure = (b×h) + (l×b)
=645.88+351.86
= 997.74 inches square
Therefore, the answer is option C
