What is the missing statement in step 3 of the proof?
given: 41 is complementary to 22
22 is complementary to 23.
prove: m21 = m23
omz1 = m22
o mx1 + m2 = 90°
o m 2 = m23
om_2 + m23 = 180°

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%

pls mark as brainliest

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.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
