For #1-4, graph the polygon with the given vertices and it's image after the transformation. label all verices in both the pre-image and image using correct notation

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

21/58.

hope to be marked brainliest

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
