Find the value of x so that the figures have the same perimeter. (MARKING AS BRAINS ST FOR PERSON WHO. GIVES THE ANSWER)

10) So here, in the first figure –

We are given a Rectangle and we know formula for perimeter of a rectangle's given

In case of 2nd figure a tiangle's given whose formula of Perimeter will be

According to the question :-

↠Perimeter of rectangle = Perimeter of triangle

↠ x+3 +x+5+x+4 = 2 (x+4+x-2)

↠ 3x + 12 = 2(2x+2)

↠ 2(2x+2) = 3x + 12

↠ 4x +4 = 3x+12

↠ 4x-3x +4-12 = 0

↠ x -8 =0

↠ x = 8

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

hello, it is c -4

hope i you have a good day
