A tree casts a shadow 31 feet long when the angle of
elevation of the sun is 58º. Find the height of the tree.
Answers
Answer:
x=24.2198542
ROUND IF NEEDED
Step-by-step explanation:
We are trying to find the height of the tree or the vertical side
We are given
The angle of elevation or the angle at the ground ,38The horizontal length, 31.Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle
we are going to use tangent
[tex] \tan(x) = \frac{opp}{adj} [/tex]
plug 38 in for x or theta, x for opp side and 31 for adjacent side
[tex] \tan(38) = \frac{x}{31} [/tex]
Multiply 31 by both sides to find x
x=24.2198542
ROUND IF NEEDED.

Answer:
x = 18.0
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these types of problems are easy.

x sin 51 = 14
x = 14/sin 51 = 18.0
A. Ana bought a table having an area of
(x2 + 10x + 25)square meters. If the
table is a square, what is the measure
of its side?
Answers
Answer:
The side length of the table is x + 5
Step-by-step explanation:
To solve this, you need only take the square root of the area:
[tex]\sqrt{x^2 + 10x + 25}\\= \sqrt{(x + 5)^2}\\= x + 5[/tex]
So the side length of the table is x + 5

Answer and Step-by-step explanation:
So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.
Now, the semicircles. They together form a circle.
So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852
Now we add them together.
99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)
The rectangle area is 3180.
The Semi circles' combined area is 99.85.
The total area of the figure is 3279.85.

What is an improper fraction?A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.
Given:
You have 5[tex]\frac{3}{4}[/tex] cups of sunflower seeds and 1[tex]\frac{1}{4}[/tex] cups of peanuts for birdseed.
The total mixture,
= 5[tex]\frac{3}{4}[/tex] + 1[tex]\frac{1}{4}[/tex]
= 23/4 + 5/4
= 28/4
= 7 cups.
You use 2/3 of the total mixture each week.
That means,
the number of weeks,
= 7 x 3/2
= 21/2
= 10.5 weeks.
Therefore, the mixture will last till 10 and a half weeks.
