HELP! If cot0 = 4/3, find csc 0.

d

Step-by-step explanation:

csc²θ-cot²θ=1

csc²θ-(4/3)²=1

csc²θ=1+16/9=25/9

cscθ=√(25/9)=5/3

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
