Step-by-step explanation:

The formula for the Simple interest is given as: = PRT

Since we've been given some values already, we slot it into the formula and this will be:

Interest = PRT

78.12 = 217 × 6% × T

78.12 = 217 × 0.06 × T

78.12 = 13.02T

T = 78.12/13.02

T = 6

Time = 6 years

step-by-step explanation:

i got the answer right on edg.

congruent: (geometry) (of figures) identical in form; coinciding exactly when superimposed.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
