Using the Pythagorean Theorem, the values of x are given as follows:
First triangle: x = 12.Second triangle: x = 21.What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
Hence, in the first triangle:
x² + 35² = 37²
x² = 37² - 35²
x² = 144
x = sqrt(144)
x = 12.
On the second triangle, we have two right triangles, hence:
x = a + b.
a² + 8² = 10²
a² = 36
a = sqrt(36)
a = 6.
b² + 8² = 17²
b² = 225
b = sqrt(225)
b = 15.
Hence the value of x is given as follows:
x = a + b = 6 + 15 = 21.

Exponential Form
We've all heard the term "exponential." What does that word mean? Exponential means growing faster and faster. However, in mathematics, it represents a formula with one or more exponents. So, we know it as exponential form. I would say that things can grow exponentially as the items being talked about get bigger and faster and faster.
So, we use the following method to write the given expression in exponential.

A savings account pays 4.62% annual interest, compounded continuously. After approximately how many years will a principal of $ 500 double?
Answers
After approximately 16 years, the principal amount of $500 double.
What do we mean by compound interest?Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate multiplied by the number of compound periods multiplied by one. The total initial loan amount is then deducted from the resulting value. The amount of interest added in each compounding period is determined by the interest rate, compounding period, and account balance. The basic formula is as follows: added interest = (interest rate for one period) × (balance at the beginning of the period).So, to find out how many years will a principal of $ 500 double:
Let x be the principal amount.The formula for calculating compound interest is as follows:
A = P(1 + r)^tThe value of r is 0.0462. In the equation, substitute this and x:
2x = x(1 + 0.0462)^t2 = (1.0462)^t (1.0462)^16 = (1.0462)^t t = 16Therefore, after approximately 16 years, the principal amount of $500 double.

8. If mZABC is one degree less than three times mZABD and m2DBC = 47°, find each measure.
Answers
The measured angle ABD=24° and ABC=71°
The figure in the question is either a triangle or a quadrilateral, but this has not been stated. It is possible to solve this regardless of shape. The accompanying graphic shows the two potential shapes and angles.
Now, based on the information provided, we may deduce that line BD divides angle ABC into two parts: Angle ABC is equal to angle ABD plus angle DBC.
Additionally, we know that angle DBC is 47 degrees and angle ABC is 1 degree less than 3 times angle ABD.
Angle ABC Equals 3x-1 if angle ABD is x.
Angle ABC also equals Angle ABD plus Angle DBC.
Changing the values in the equations above 3x-1 = x+47 ⇒ 2x = 48⇒ x = 24
Angle ABD thus equals 24 degree, and angle ABC = 3(24)-1 = 71-1 = 71 degree
∴∠ABD=24° and ∠ABC=71°

The slope of the line is 1 / 3
How to find the slope of a line?The slope of a line is a measure of its steepness.
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
Mathematically, the slope of a line can be described as follows;
slope = change in y / change in x
Therefore,
slope = y₂ - y₁ / x₂ - x₁
Let's take two points from the graph
(0, 2)(3, 3)
where
x₁ = 0
x₂ = 3
y₁ = 2
