Please help me. Thanks in advance

yes no yes should be right tell me if i wrong

Step-by-step explanation:

Step-by-step explanation:

y ≤ − x /4 + 5 is boundry

line is not dashed

plane is below boundry line

x + 4/7

step-by-step explanation:

use cymath

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
