Suppose a linear transformation l is represented by the matrix −1
3 1

find a point l
xy
so that l

=

the first one, all those points on the line just make a strait line.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

0

step-by-step explanation:

equals the constant of proportionality.
