Remember

  • Its a dilation so the ratio of corresponding sides remains same like before .

So

  • All trigonometric ratios are also same in both traingles

Or

\\ \rm\hookrightarrow \dfrac{AB}{BC}=\dfrac{XZ}{YZ}

  • Hence sine is equal
  • So all trigonometric functions are also equal

#B

  • cosX=Base/Hypotenuse
  • cosA=AC/AB

So

  • AC equal to 2.05
  • AB=5.59

Jack reads his book for 8 minutes before school and 10 minutes after school. he attends school monday through friday. write an e
Maslowich

Answer:

180 min

Step-by-step explanation:

The first thing is to get the number of days in two weeks that he would read the book, since he only does it when he goes to school. School goes from Monday to Friday, that is to say 5 days, how two is two weeks would be a total of 10 days. Mathematically, it would be the equation, where X would be the number of minutes inside the parentheses and the minutes read before and after school:

X = 10 * (10 + 8)

Solving:

X = 180

In other words, in two weeks he has read a total of 180 minutes.
