Answer:

Step-by-step explanation:

Exterior angle of a triangle is equal to the sum of opposite interior angles

13b - 48 = (9b - 47) + (b + 44)

Add the like terms

13b - 48 = 10b - 3

Add 48 to both the sides

13b - 48 +48 = 10b - 3 +48

13b = 10b + 45

Subtract 10b from both sides

13b - 10b = 10b + 45 - 10b

3b = 45

Divide both sides by 3

3b/3 = 45/3

b = 15

Answer:

b=15

Step-by-step explanation:

Since the angle with measurement is the exterior angle than the the two other angles added up are equal to it. When you add it up it becomes a simple equation where b=15.

Please help me. I desperately need to pass Math T-T​
Ad libitum [116K]

Answer:

60 degrees

Step-by-step explanation:

C = 2(pi)r

The radius is 12 cm. We can find the circumference of a circle with radius 12 cm.

C = 2(pi)r = 2(3.14)(12 cm) = 75.36 cm

The length of the arc of the sector is 12.56 cm.

We can find the fraction this length is of the full circumference.

(12.56 cm)/(75.36 cm) = 1/6

The length of the arc of this sector is 1/6 the length of the circumference of the entire circle.

That means the angle of the sector is 1/6 the angle of an entire circle.

An entire circle has a central angle of 360 degrees.

1/6 * 360 degrees = 60 degrees
