The number of years was his money inversted is;

\rm I= P\times r \times t

Where p is the principal amount, r is the rate of interest, I is the amount and  t is the time.

Substitute all the values in the formula;

\rm I= P\times r \times t\\\\2200-1000= 1000 \times .08 \times t\\\\1200 = 80t\\\\t = \dfrac{1200}{80}\\\\t=15

The following is an incomplete paragraph proving that the opposite angles of parallelogram ABCD are congruent: Parallelogram ABC
Studentka2010 [4]

General Idea:

The angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. The theorem says that when the lines are parallel, that the alternate interior angles are equal.

Applying the concept:

Angles PBC and BAD are congruent by the <u>Corresponding Angle Theorem</u>.

Angles ABC and BAT are congruent by the <u>Alternate Interior angle Theorem</u>.
