Find the exact values of sin(\theta )/(2) and cos(\theta )/(2) for sin\theta =(1)/(3) on the interval 0\deg <=\theta <=90\deg .

(-5,-28)

i graphed to on desmos.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

x = 3 ± √(5+y)

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
