Find the area of the figure with Heron’s formula
Answers
Answer:
735 cm²
Step-by-step explanation:
The figure is a trapezium .The area of the triangle section can be calculated using the Heron's formula.
The other part of the figure will be a square of sides 21 cm by 21 cm
Area of the square section
Area = l²
Area = 21* 21 = 441 cm²
Area of the triangle using Heron's formula
Sides of the triangle are ;
a= 28 cm
c= 35 cm
b = 21 cm -----height of the trapezium
The Heron's formula is given as;
[tex]A=\sqrt{s( s-a)(s-b )(s-c )}[/tex]
where s is half the perimeter of the triangle
Perimeter of the triangle is given as ;
P= 35 + 28 + 21 =84 cm
s= 84/2 = 42 cm
[tex]A=\sqrt{42*(42-21 )*(42-35 )*(42-28 )} \\\\A=\sqrt{42*(21 )*(7 )*( 14)} \\\\A=\sqrt{86436} \\\\A=294\\\\[/tex]
Total area = 294 + 441 = 735 cm²
Which of the following lists of numbers is closed under division?
O Rational Numbers
O Whole Numbers
O Natural Numbers
O Irrational Numbers
Answers
Answer:
The set of rational numbers is closed under addition, subtraction, multiplication, and division (division by zero is not defined) because if you complete any of these operations on rational numbers, the solution is always a rational number
Step-by-step explanation:
Rational Numbers closed under division
What are rational numbers?Rational Numbers: Any number that can be written as a ratio (or fraction) of two integers is a rational number.
Given:
we have to find the Numbers closed under division
Whole numbers are not closed under division because denominator can't be equal to 0.
Similarly, Natural Numbers and Irrational Numbers are not closed under division.
Since the result of any of these operations on rational numbers is always a rational number, the set of rational numbers is closed under addition, subtraction, multiplication, and division (division by zero is not defined).

Approximate Value Exact Value Error Absolute Error Ratio Percent Error
$100
$75
$25
How much was the absolute error in his estimate?
$
Intro
Answers
Answer:
Absolute error = $25
Step-by-step explanation:
Given that:
Amount spent by John on shopping trip = $75
Estimated amount to spent on shopping trip = $100
Absolute error = Approximate value - Exact value
Here,
Approximate value = $100
Exact value = $75
Absolute error = 100 - 75
Absolute error = $25
Percentage = [tex]\frac{Absolute\ error}{Exact\ value}*100[/tex]
Percentage = [tex]\frac{25}{75}*100[/tex]
Percentage = 33.33%
Hence,
Absolute error = $25

If P is the incenter of triangle JKL, find the measure of JKP.
Answers
Answer:
m∠JKP = 31.5°
Step-by-step explanation:
Incenter of a triangle is the point where all the bisectors of interior angles intersect each other.
JN is the angle bisector of ∠KJL.
Therefore, m∠KJN = m∠LJN
(7x - 6) = (5x + 4)
7x - 5x = 6 + 4
2x = 10
x = 5
m∠KJN = (7x - 6)
= 7(5) - 6
= 35 - 6
= 29°
In ΔKJN,
m∠JKN + m∠KNJ + m∠NJK = 180°
m∠JKN + 90° + 29° = 180°
m∠JKN = 180°- 119° = 61°
Since KO is the angle bisector of ∠JKN,
m∠JKP = [tex]\frac{1}{2}(\angle JKN)[/tex]
= [tex]\frac{1}{2}(61)[/tex]
= 30.5°

Given m ||n, find the value of x.
(7X+9)
(9x+5)°
Answers
Answer:
x = 2Step-by-step explanation:
(7x + 9)° is corresponding angle to (9x + 5)° angle
Therefore:
m║n ⇒ (7x + 9)° = (9x + 5)°
(7x)° + 9° = (9x)° + 5° {subtract (7x)° from both sides}
9° = (2x)° + 5° {subtract 5° from both sides}
4° = (2x)° {divide both sides by 2°}
x = 2
