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.

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

Find the area of the figure with Heron’s formula
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?
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

2) 11 = p
3) 4 = -k
Step-by-step explanation:
I will not help you with every question, but I will help you with a few and explain the process so you can understand.
1 ) 15 = c + 4
11 = c
## Subtraction Property Of Equality (Subtract 4 from both sides)
2) 7 = p - 4
11 = p
## Addition Property Of Equality (Add 4 to both sides)
3) -2 = -k/2
4 = -k
## Multiplication Property Of Equality (Multiply both sides by -2)

How to find the function which was used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
A graph titled Sales has a month on the x-axis and sales (dollars times 1,000) on the y-axis.
Mary: Starts at 6.4 and ends at 8.6.
Lewis starts at 5.5 and ends at 6.9.
Todd: Starts at 4.6 and ends at 3.3.
Paige: Starts at 7.1 and ends at 7.1.
The difference between the start sales and end sales represents the greatest decline.
Here, Paige has the least difference.

If P is the incenter of triangle JKL, find the measure of JKP.
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°
