The coordinates rotated 180° clockwise. Write the coordinates after rotation.

T (3,8 ) T’ (-3, 8)
R(-5, 9) R’ (, )
S(-2, 3) S’ (2,-3 )

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

answer: what statements

step-by-step explanation if you write the statements down then i could you.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

wait nvm i know the correct answer now its 100%   81 square feet
