What is the relation between adjacent and congruent angles?.

1 answer:

5 0

Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex. Adjacent angles share a common ray and do not overlap. The size of the angle xzy in the picture above is the sum of the angles A and B.

A deposit of $2,630 is placed into a retirement fund at the beginning of every 6 months for 11 years. The fund earns 3% annual i

Answer:

FV= $67,952.83

Step-by-step explanation:

Giving the following information:

Semiannual deposit= $2,630

Number of periods= 11*2= 22 - 1= 21

Interest rate= 0.03/2= 0.015

We need to determine the future value at the last deposit. We will use the following formula:

FV= {A*[(1+i)^n-1]}/i + {[A*(1+i)^n]-A}

A= semiannual deposit

FV= {2,630*[(1.015^21) - 1]} / 0.015 + {[2,630*(1.015^21)] - 2,630} + 2,630

FV= 64,357.47 + 965.36 + 2,630

FV= $67,952.83

Check the attachment for the diagram.

You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;

tan 35° = opposite/adjacent

tan 35° = AB/BC

tan 35° = AB/100

AB = 100tan35°

AB = 100 * 0.7002

AB = 70.02m

Hence the distance across a lake between A and B is approximately 70m
