Answer:
The answer to 5 2/11 - 3 2/18 is 2 7/99
Step-by-step explanation:
The formula is
L = rC where L = length of the arc, r = radius of the circle and C is the angle in radians.
here r = 4 and C = 110pi / 180
arc length L = (4 * 110 * pi) / 180 = 7.7 ins
A quadratic equation cannot have one imaginary solution because of the discriminant enclosed in a radical. The discriminant, √(b² - 4ac), determines the nature of the roots and it can only be either 2 real roots, 1 real solution or 2 imaginary roots. Hope this answers the question.
Yz is the 5 part of the 4:5
20=5 units
divide by 5
4=1 unit
bc is the coresponding side that is 4 units
4 times 1 unit=4 times 4=16 units long is side bc
bc=16 units
