Using the fact that cos(52) = 0.6157, find the measure of angle B if sin(B) = 0.6157.
Answers
Answer: B = 38
===============================================
Work Shown:
If cos(A) = sin(B), then A+B = 90, where A & B are both acute angles in degree form.
In this case, A = 52, so,
A+B = 90
B = 90-A
B = 90-52
B = 38
Telling us that
cos(A) = cos(52) = 0.6157
sin(B) = sin(38) = 0.6157
cos(52) = sin(38)

Henry deposits $25,000 into a Big City Bank savings account. The bank charges a simple interest rate of 2.25%. After 5 years, Henry will have $27812.5 in his account.
What exactly is an interest rate example?
- It is the annual rate charged for borrowing (or made by investing), expressed as a single percentage number that represents the actual yearly cost of funds over the loan's term.
- For example, if you borrow $100 at 5% interest, you will pay back $105 to the lender. The lender will profit by $5.
- Throughout your life, you may develop a variety of interests. Every loan has its own interest rate, which determines the total amount owed.
- We can calculate the interest rate using the interest rate formula, which is the percentage of the principal amount charged by the lender or bank to the borrower for the use of its assets or money for a specific time period. Interest Rate = (Simple Interest 100)/(Principal Time) is the interest rate formula.
Given,
P = 25000 r = 2.25%
t = 5
Replace the formula,
F = 25000 + 25000 × ( 2 .25/100) × 5
Calculate the quotient or product:
25000 × (1 + 0.1125)
Simplifying,
25000 × 1.1125
Calculate the quotient or product:
27812.5
Hence, After 5 years, Henry will have $27812.5 in his account.

Given:
Intercepted arcs of small circle:
78° and x°
Intercepted arcs of large circle:
57° and 121°
To find:
The measure of angle formed by two secants and the value of x.
Solution:
Consider a large circle:
The angle made by two secants intersecting outside a circle is half the difference between the measure of intercepted arcs.
The measure of the angle formed by two secants is 32°.
Two circles are concentric circles.
Therefore 32° is also the angle made by small circle arcs.
Multiply by 2 on both sides.
Add 78° on both sides.
The value of x is 124.
