Sylvia’s aunt asked her to cut out fabric for a quilt. the figure shows the pattern of one section that is made of triangles.
what degree of rotation clockwise about point b should sylvia use to prove that δabc (pre-image) and δibh (image) use the same amount of fabric?
clockwise

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1

1. ∠1 is complementary to ∠2 and ∠3 is complementary to ∠2. subtraction property of equality 2. m∠1 + m∠2 = 90 and m∠3 + m∠2 = 90 substitution 3. m∠1 + m∠2 = m∠3 + m∠2 definition of complementary 4. m∠1 = m∠3 given
