The given proportion of triangle ABC as AE/AD = EB/DC is; Not Accurate
Understanding Basic proportionality theorem(Thale's Theorem)This theorem states that If a line is drawn parallel to one side of a triangle, then it cuts other two sides proportionally.
Thus, In ΔABC, DE || BC
By Thales theorem, we can say that;
AD/DB = AE/EC
Rearranging we can arrive at;
AE/AD = EC/DB
When we simplify further by adding 1 to both sides, we will get;
AD/AB = AE/AC
Thus, the given proportion is not accurate

In the triangle shown above, a = 16 cm, b= 12 cm, and c= 8 cm. What is the approximate measure of angle A?
A. 14.48°
B. 75.52°
C.65.56°
D.104.48°
Answer:
I think its A
Step-by-step explanation:
The approximate measure of angle A is 104.48 degrees. The correct option is D.
Given that:
a = 16 cm
b = 12 cm
c = 8 cm
To find the measure of angle A in the triangle, use the law of cosines.
The law of cosines states that for any triangle with sides a, b, and c, and the angle opposite side c, denoted as C:
c² = a² + b² - 2ab × cos(C)
In this case, we want to find angle A, which is opposite side a. So, the equation becomes:
a² = b² +c² - 2bc × cos(A)
Now, plug in the given values:
16² = 12² + 8² - 2 × 12 × 8 × cos(A)
256 = 144 + 64 - 192 × cos(A)
Now, isolate cos(A):
192 × cos(A) = 144 + 64 - 256
192 × cos(A) = -48
cos(A) = -48 / 192
cos(A) = -1/4
Now, to find the measure of angle A, take the inverse cosine (cos^-1) of -1/4:
[tex]A \approx cos^{-1(-1/4)}[/tex]
A ≈ 104.48 degrees.
So, the approximate measure of angle A is 104.48 degrees. The correct option is D.

what are the solutions to this polynominal when s(x) =0 s(x) (3x^2 + 17x+10 )(x-7)(4x-3) enter your answers in the boxes, from least to greatest.
Answer:
-5, -2/3, 3/4, 7
Step-by-step explanation:
The solutions are solutions of one of the following:
(3x^2 + 17x + 10) = 0, x - 7 = 0, 4x - 3 = 0
The latter two are straightforward: x = 7 or 3/4.
To factor the first, note it must be of the form (3x + __) (x + __)
Check the pairs (10, 1) (1, 10) (5, 2) and (2, 5) and we find:
(3x + 2) (x + 5) = 0

A deck is shaped like a parallelogram with a base length of 27 feet and a height of 11 feet. A can of wood stain will cover 40 square feet.
How many cans of stain will be needed to stain the deck?
Enter your answer in the box.
From the area of the parallelogram, it is found that 8 cans of stain will be needed to stain the deck.
What is the area of a parallelogram?The area of a parallelogram of base length l and height h is given by:
A = lh
In this problem, the dimensions are l = 27, h = 11.
Hence, the area, in square feet, is given by:
A = 27(11) = 297.
Each can cover 40 square feet. How many cans are needed for 297 square feet?
[tex]n = \frac{297}{40} = 7.425[/tex]

A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles. What is the probability of exactly seven out of the next eight tires lasting over 3,000 miles?
(Round your answer to three decimal places.)
Answer:
A manufacturing corporation make tires with a probability 0.77 of lasting over 3,000 miles.
Step-by-step explanation:
The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be 0.32.
How to find that a given condition can be modelled by binomial distribution?Binomial distributions consist of n independent Bernoulli trials.
Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))
The probability that out of n trials, there'd be x successes is given by
