∵ The sum of all angles of triangle = 180°
∴ m∠B + m∠C + m∠D = 180°
R3. Their sum = 180 (They form straight angle)
S4. ∠B + ∠A = 180°
R5. Triangle angle sum theorem (Sum of all angles of triangle = 180°)

in 2000 the population of India was around 1.053 billion , and in 2016 the population hit 1.327 billion people . if India's population continues to grow at this same rate in what year was the population of India reach 3 billion people.
Answers
Answer:
The population of India would reach 3 billion in about 112 years (year 2128)
Step-by-step explanation:
1. subtract 1.327 billion by 1.053 billion (1.327-1.053)
2. The answer you should get is 274,000,000 (two hundred seventy four million)
3. multiply 274,000,000 by 7 (amount of people required to reach about 3 billion)
4. add the product (ans to multiplication problem) to 1.327 billion. (you should get 3.245 billion (3245000000).
5. multiply 16 by 7 (16x7) to get the number of years to reach 3 billion (maybe 112)
6. Add the product to 2016
7. Therefore you get the year 2128.

Using Cramer's Rule, the solution to the system of equations
6x−5y=−4−7x+3y=−1
can be written in the form (DxD,DyD).
What is the value of Dx?
Answers
Using Cramer's rule it is found that Dx = -34.
In Cramer's rule, we have three matrices.
x is a matrix in which the first column is the coefficients that multiply x, and the second are the coefficients on the right side of the equality.y is a matrix in which the first column is composed by the coefficients on the right side of the equality and the second is the coefficients that multiply y.M is a matrix in which the first column is the coefficients that multiply x, and the second is the coefficients that multiply y.In this problem, the system is:
[tex]6x - 5y = -4[/tex]
[tex]-7x + 3y = -1[/tex]
Matrix x is given by:
[tex]x = \left[\begin{array}{ccc}6&-4\\-7&-1\\\end{array}\right][/tex]
It's determinant is given by:
[tex]Dx = 6(-1) -(-4)(-7) = -6 - 28 = -34[/tex]
Thus, Dx = -34.

2,631 dividido entre 24
Answers
Answer:
2631 divided by 24 = 109.625
Step-by-step explanation:
The result of 2631/24 is a terminating decimal with 3 digits to the right of the decimal point.
2631 divided by 24 in decimal = 109.625
2631 divided by 24 in fraction = 2631/24
2631 divided by 24 in percentage = 10962.5%
Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 2631 and 24, of course.
Repetends, if any, are denoted in ().
The conversion is done automatically once the nominator, e.g. 2631, and the denominator, e.g. 24, have been inserted.

if x 60 and 30 find the unknown sizes of angle
Answers
Answer:
A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any missing part of the triangle. The ratio of the side lengths of a special right triangle with angles of 30, 60, 90 is 1:sqrt(3):2, while the ratio of the side lengths of a special right triangle with angles of 45, 45, 90 is 1:1:sqrt(2).

Answer:
x = 2
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{7x}{7}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
7x² = 28 ( divide both sides by 7 )
x² = 4 ( take square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2

Therefore EHI must be 20 degrees.
angles DIG and EIH are congruent angles because CD is a straight line.
Therefore EIH must be 60 degrees.
Now that you know two of the three angles in the triangle HEI,
Total degrees in a triangle - EIH - EHI = HEI
