Solve and show work! ! i believe i have the right answer but i want to make sure

t = 51

Step-by-step explanation:

Given

360 = 20 ( divide both sides by 20 )

18 = ( square both sides )

18² = t + 273, that is

t + 273 = 324 ( subtract 273 from both sides )

t = 51

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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.
