One method to find angle B is A. use the Pythagorean theorem to find BC, then solve the equation tan(B)=8/BC.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given is a right angled triangle ABC with the hypotenuse being AB and the legs AC is the base and BC is the height.
Given AC = 8 and AB = √89.
We need to find the measure for angle B.
Either we can find angle B using Sin B = Opposite side / hypotenuse
Sin B = 8 / √89
But this is not in the option.
So first find the length of BC using the Pythagoras Theorem.
(BC)² = (AB)² - (AC)²
= (√89)² - (8)²
= 25
BC = √25 = 5
We get the opposite side and adjacent side with respect to angle B.
Tan B = AC / BC = 8 / 5 = 1.6
B = 57.99° ≈ 58°
Hence the approximate measure of angle B is 58°.

You have 2 different savings accounts. For Account A, the simple interest earned after
6 months is $4.63. For Account B, the simple interest earned after 21 months is $16.80. If the interest rate is 3.7% for Account A and 2.4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount of money invested.
R represents interest rate
T represents time
Considering the investment on account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years
6.94 = (P × 3.7 × 0.75)/100 = 0.02775P
P = 6.94/0.02775 = $250
Considering the investment on account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
13.8 = (P × 2.3 × 1.5)/100 = 0.0345P
P = 13.8/0.0345 = $400
To determine the account that earned more interest in the first month,
250/9 = $27.8
400/18 = $22.2
Account A earned you the most interest the first month because $27.8 is higher than $22.2

Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.
Answer:
[tex]D' = (-4,-6)[/tex] and [tex]D' = (-4,8)[/tex]
Step-by-step explanation:
Given
[tex]D(x,y) = (-4,1)[/tex]
Required
Determine a point 7 points from D and in the same x coordinate
Represent this point with D'.
From the requirement of the question, D' has two possible values and these values are:
[tex]D' = D(x,y-7)[/tex] ----> 7 units down and
[tex]D' = D(x,y+7)[/tex] ----> 7 units up
Substitute values for x and y in [tex]D' = D(x,y-7)[/tex] and [tex]D' = D(x,y+7)[/tex]
So, we have:
[tex]D' = D(x,y-7)[/tex]
[tex]D' = (-4,1 - 7)[/tex]
[tex]D' = (-4,-6)[/tex]
[tex]D' = D(x,y+7)[/tex]
[tex]D' = (-4,1+7)[/tex]
[tex]D' = (-4,8)[/tex]
PLEASE HELP ME ANSWER The probability that Scott will be late for work is 0.15. In a year Scott works for 240 days. Work out the expected number of days that he will be late......

Answer:
8units²
Step-by-step explanation:
Area of the trapezoid = 1/2(a+b)h
a and b are the opposite sides
h is the height
Take a square as 1 unit
a = 1 unit
b = 3 units
height h = 4 units
Substitute
A = 1/2(1+3)*4
A = 1/2 * 4 * 4
A = 16/2
A = 8units²
Hence the area of the trapezoid is 8units²

An infinite number of ratios are equivalent to 3:8. How
can that be possible, when the multiplication table only
goes to 9?
Answer:
See below, please!
Step-by-step explanation:
There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.
For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?
