Greg is at his house. He gets in the car and drives north 7.4 miles and stops at the store. Then he drives 5.7 miles south to his friend's house. How far is the friend's house from Greg's house? Group of answer choices

2.7 miles

1.7 miles

13.1 miles

42.18 miles

Given:

Greg drives north 7.4 miles and stops at the store.

Then he drives 5.7 miles south to his friend's house.

To find:

The shortest distance between Greg's house and his friend's house.

Solution:

Greg drives north 7.4 miles.

He drives 5.7 miles south.

The shortest distance between Greg's house and his friend's house is difference between distance he drives north and distance he drives south.

Shortest distance = (7.4 - 5.7) miles

                             = 1.7 miles

The shortest distance between Greg's house and his friend's house is 1.7 miles.

Therefore, the correct option is C.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
