Exercise 6 1
Solve for x by completing the square;
a
x² - 2x - 4 = 0
bu x2 - 4x - 2 = 0
С x2 + 8x + 5 = 0
X x² + 22x - 150
e
x2 - 7x + 10 = 0
f x² + 5x-2=0
g x2 + 9x - 4 = 0
h x2 - 3x - 6 = 0​

add 5 subtract 1

step-by-step explanation:

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
