5 lollipops and 12 toffees have a mass of 61 grams 10 lollipops and 13 toffees have a mass of 89 grams

(i) If the mass of one lollipop is x grams and the mass of one toffee is y grams, write two equations
in x and y to represent the above information.
(ii) calculate the mass of
a) one lollipop
b) one toffee

a

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

answer: it is a.,b.,d.
