To make getting to BWI easier we are going to use a shuttle service. due to an accident on I-195 we will get on the Baltimore beltway (I-695) at Exit 12B, Wilkins Avenue and take it to exit 7 the Baltimore Washington Parkway (MD 295). Assuming the beltway is a perfect circle with a radius of 7.79 miles and the angle between exit 7 and exit 12B is 0.513 radians: A. Find the distance we traveled on the beltway. (Draw relevant diagram.) B. If our average driving speed was 59mph how long did it take us to travel from exit 7 to exit 12B?​

the axial of symmetry

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
