What is sin A?.

Your required answer is option A.

Step-by-step explanation:

Hey, there!!!

The given figure is Triangle ABC.

where, AB= 17.

BC= 8

AC = 15.

As it is a Right angled triangle, taking angle theta as a refrence angle.

we get,

h = 17

p= 8

b= 15

we know that,

ratio of sin = p/h

or, sin theta = 8/17

Therefore, the value of x is 0.4705882353.

Hope it helps...

what is the original number? you forgot to add it.

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.
