Answer:

1) x = 3

y = 42

2) x = 50

y = 70

Step-by-step explanation:

1) 12x + 6 = 14x

6 = 2x

x = 3

14(3) = y

42 = y

2) 2x + 10 + x + 20 = 180

3x + 30 =180

3x= 150

x=50

2(50)+10=110

110-180

y=70

Determine the value of s, the arc length (measured in inches) cut off in a circle with a radius of 3.4 inches by an angle with a

AleksandrR [38]

Answer:

Arc length s = 15.3 inches

Step-by-step explanation:

We know that length of an arc that subtends an angle θ radians at the center is given by

$s=r\times \Theta$

where

r is the radius of the circle

θ is the angle subtended in radians

Thus applying values we get $s=3.4\times \ 4.5radians$

thus s = 15.3 inches
