The expression (secx + tanx)2 is the same as

The expression

Solution:

From question, given that

By using the trigonometric identity the above equation becomes,

We know that

On simplication we get

By using the trigonometric identity ,the above equation becomes

By using the trigonometric identity

we get

By using the trigonometric identity  we get

Hence the expression

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
