Kristen's school is due west of her house and due south of her friend Cooper's house. The distance between the school and Cooper's house is 9 miles and the straight-line distance
between Kristen's house and Cooper's house is 10 miles. How far is Kristen's house from
school? If necessary, round to the nearest tenth.
miles

Kristen's house is 4.4 miles away from her school

Step-by-step explanation:

Pythagora's Theorem

In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:

Where

c = Hypotenuse or largest side

a,b = Legs or shorter sides

The situation described in the problem forms a right triangle shown in the image below.

Applying Pythagora's Theorem :

Solving for x:

Kristen's house is 4.4 miles away from her school

dont understand

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
