The measure of angle A to the nearest degree is 40 degrees.
How to apply sine law?
Sine law can be used to find the measure of angle A in the triangle.
Therefore,
a / sin A = b / sin B
where
a =210
b = 164
A = ?
B = 30 degrees
Hence,
210 / sin A = 164 / sin 30
cross multiply
0.5 × 210 = 164 sin A
sin A = 105 / 164
sin A = 0.64024390243
A = sin⁻¹ 0.64024390243
A = 39.7918194996
A = 40 degrees.
In triangle ABC, angle B = 30°, a = 210, and b = 164. The measure of angle A to the nearest degree is.

What are Binomial squared?The square of a binomial is the sum of the square of the first terms, then multiply the product of the two terms after that the square of the last term.
We have,
3x² + 18x - 8= 0
Move the constants to the right side.
3x² + 18x = 8
Take Factor 3 out of the variable terms.
3(x²+6x)=8
Add 27 to both sides of the equation.
3(x²+6x+9)=8+27
3(x²+6x+9)=35
Write the polynomial as a binomial squared.
3(x+3)²=35

An engineer is designing a television screen. the screen is shaped like a rectangle with a length of 43.6 inches. the ratio of the length of the rectangle to its width must be 16:9. what is the approximate length of the diagonal of the screen?
By using the given ratio, we will see that the diagonal measures 50 inches.
How to get the diagonal of the screen?First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:
W = (9/16)*43.6 inches = 24.5 in
Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:
[tex]D = \sqrt{(43.6in)^2 + (24.5in)^2} = 50 in[/tex]

Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. which group describes 16% of the oarfish population? select each correct answer.
Answer:
Explanation:
oarfish that are shorter than 5 m
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m

The system of equations models the paths of the two skate is y = 0.08x²-1.6x+13 and y = 5(x-10)²+5. The correct option is b.
What is quadratic equation?The equation with second degree of an unknown variable x, y, m, n, or p is called the quadratic equation.
David starts at (20, 13) and skates along a path that can be modeled by a quadratic equation with a vertex at (10, 5).
Vertex form of quadratic equation is
y =a (x -h)² +k where (h,k) is the vertex.
We plug in (10,5) for h and k
y= a (x -10)² +5
Now plug in (20,13) in the above equation and find out 'a'
13 = a (x -10)² +5
13 = a(10)² +5
13 = 100a + 5
Solving for a, we get
a = 0.08
Substitute 0.08 for 'a' then the equation becomes
y= 0.08 (x -10)² +5
Thus, the correct option is b.

If r is a commutative ring, show that the characteristic of r[x] is the same as the characteristic of r.
If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
What is a commutative ring?In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.
Let R represent a commutative ring with characteristic K.
Therefore, we have: Kr = 0∀r ∈ R.
Assuming f(x) ∈ R(x)
Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]
Also, in some instances ai ∈ R and n ∈ N.
Finally, we would have:
[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]
Kf(x) = 0.
Therefore, we can infer and logically deduce that if R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.

The tree in jacob's yard casts a shadow that is 27 feet long. jacob is 5 feet tall and casts a shadow that is 4.5 feet long. the two triangles formed are similar because the angle to the sun is the same. what is the height of the tree?
By using the fact that the two triangles are similar, we will conclude that the height of the tree is 30ft
How tall is the tree?
If the two triangles are similar, then the quotient between the height and the shadow length must be the same for both of them.
Then if H is the height of the tree we can write:
H/27ft = 5ft/4.5ft
Now we can solve this for H, we will get:
H = (5ft/4.5ft)*27ft = 30ft
So we can conclude that the height of the tree is 30ft.
