27= 3x3x3
54 = 3x3x3x2
so 27/54 = 3x3x3 /<span>3x3x3x2 by simplifying = 1/2</span>
We can get the measurement of the arc by determining first the radius of the circle. The circumference of a circle is equal to 2 * pi * radius. Hence from a 12 unit2 circumferenced circle, the radius is 1.91 units.Length of the arc is equal to radius times the angle in radians. 60 deg is equal to pi over 3. The length of the arc is equal to 2 units.
-8y + 9x = -5
8y + 7x = -75 +
--------------------------
/ 16x = -80
x = -80/16
x = -5
8y + 7x = -75
8y - 35 = -75
8y = -75 + 35
8y = -40
y = -40/8
y = -5
Answer : x = y = -5
To find the perimeter of irregular shapes in general, you just add the length of the sides.
To find the area of irregular shapes, first, draw a line to separate the two shapes, then find the area of those two shapes and add them up.
