Katie has to drive 15 miles east and 36 miles north to get to her aunt's house. What is the direct distance to her aunt's house?

39 miles

Step-by-step explanation:

Hi, since the travelling forms a right triangle, (see attachment) we have to apply the Pythagorean Theorem formula.

a^2 +b ^2 =c ^2

Assuming a and b are the distances driven, and c the direct direction formed (hypotenuse)

15^2 +36 ^2 =c ^2

225+1,296 =c ^2

1,521 =c ^2

√1,521= c

c= 39 miles

Feel free to ask for more if needed or if you did not understand something.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

a c
