Can someone tell me the answer
Rzqust [24]

Answer:

A. 9/25

Step-by-step explanation:

There are a total of 25 T-shirts, which means that the denominator of the fraction is going to be 25 (which already rules out B and C). In the information they give us, they said that there are 9 red shirts. Therefore, the numerator will be 9. Our complete fraction is 9/25, or A.

I hope this helps! Have a lovely day!! :)

Identify the correct justification for each step, given that ∠2 and ∠3 are complementary, and m∠1=m∠3.
blondinia [14]

Answer:

Option A is correct because sum of m<2 and m<3 are complementary. So m<2+m<3 =90° .

Step-by-step explanation:

Given: <2 and <3 are complementary angles.

Definition of complementary angles says if two angles sum is equal to 90 degrees then they are called complementary angles.

Statement                                                       Reason

1.<2 and <3 are complementary                 1. Given

2. m<2+m<3 =90°                                         2. Definition of complementary <s

3. m<1= m<3                                                  3. Given

4. m<1+m<2= 90°                                          4.Substitution property of =

5. <1 and <2 are complementary               5. Definition of complementary <s.

Option A matches with the given. We can not use addition properties of equality for statement 2 so, other options are incorrect.

So, according to the given options A is correct.
