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°

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

Describe how each graph is obtained from the graph of y= f(x).

(a) y = f(x – 2)

Can somebody help telling what does it mean? what does it want us to do? ​

Answers

Answer:

see explanation

Step-by-step explanation:

Give the graph of y = f(x) then y = f(x + a) represents a horizontal translation of y = f(x)

• If x > 0 then a shift to the left of a units

• If x < 0 then a shift to the right of a units

Thus

y = f(x - 2) is the graph of y = f(x) translated 2 units right

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).

Given m ||n, find the value of x.
(7X+9)
(9x+5)°

Answers

Answer:

         x = 2

Step-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

What is area of isosceles triangle?

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

Area: ½ × base × height

here, we have,

the side= 18, 18

base = 14

here, it is a isosceles triangle.

So, using the formula ,

we get,

area= 116.06

hence, A≈116.06,  the area of the triangle.
