A building casts a 32m shadow when the sun is at an angle of 30 degrees to the vertical. How tall is the building to the nearest meter?
Answer:
16m tall
Step-by-step explanation:
Distance casted by the shadow = 32m = hypotenuse
Angle of elevation = 30 degrees
Required
Height of the building = opposite
Using the SOH CAH TOA identity
sin theta = opp/hyp
sin 30 = x/32
0.5 = x/32
x = 0.5 * 32
x = 16m
Hence the building is 16m tall

USE ARITHMETIC OR GEOMETRIC SEQUENCE TO SOLVE.
Lisa wants to get a new phone. An iPhone 12 is $800 while an iPhone 8 is $600. If the iPhone 12's price goes down by 10% each year and the iPhone 6's goes down by 5% each year, Which phone would be the cheapest for Lisa to get after three years?
Answer:
iPhone 12!!!!!!!!!!!!
Answer:
The iphone 8
Step-by-step explanation:
To find the nth term of a geometric sequence we have the following equation
ar^(n-1)
where a is the first term
r the is the common ratio
n is the term
we can see that the first term for the iphone 12 is 800, the common ratio is .9 (1-.1), and we need the third term
Therefore the price of an iphone 12 after 3 years is
800*.9^(3-1)
which is 648
The iphone 8's first ter is 600 and the common ratio is .95 (1-.05)
using the same equation
600*.95^(3-1)
which is 541.5
What relationship do you notice between the squares of
the right triangle?
The special relationship that exists between the squares of the lengths of the sides of a right triangle is known as the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse.

The distance of 15 miles on a map is represented by 2 inches. If the distance between two cities on the map is 8 inches, write a proportion to determine the actual distance between them?
The actual distance between the two cities is 60 miles.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The distance of 15 miles on a map is represented by 2 inches.
This means,
2 inches = 15 miles
Divide both sides by 2.
1 inch = 7.5 miles
Multiply 8 on both sides.
8 inches = 8 x 7.5 miles
8 inches = 60 miles
Thus,
The actual distance is 60 miles.

THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE PARALLELOGRAM
Answer:
The adjacent angles are: 72 and 108
Step-by-step explanation:
Given
Angle Ratio = 3 : 2
Required
Find the measure of each angle
Let the angles be [tex]x\ and\ y.[/tex]
Such that:
[tex]x + y = 180[/tex] --- adjacent angles of a parallelogram
and
[tex]x : y = 3 : 2[/tex] --- given
Convert to fraction
[tex]\frac{x}{y} = \frac{3}{2}[/tex]
Cross Multiply:
[tex]2x = 3y[/tex]
Make x the subject:
[tex]x = \frac{3}{2}y[/tex]
[tex]x + y = 180[/tex] becomes
[tex]\frac{3}{2}y + y = 180[/tex]
Take LCM
[tex]\frac{3y + 2y}{2}= 180[/tex]
[tex]\frac{5y}{2}= 180[/tex]
[tex]y = \frac{2}{5} * 180[/tex]
[tex]y = 0.4 * 180[/tex]
[tex]y = 72[/tex]
Recall that:
[tex]x = \frac{3}{2}y[/tex]
[tex]x = \frac{3}{2} * 72[/tex]
[tex]x = 1.5 * 72[/tex]
[tex]x = 108[/tex]
Hence, the adjacent angles are: 72 and 108
