In this triangle by applying Pythagoras theorem.
H²=B²+P²
18²=15²+P²
324=225+p²
324-225=P²
√99=p
9.94
Answer:
17 inches
Step-by-step explanation:
it's 17 because x² = 15² + 8²
then x² = 225+64 which is x² = 289 so now you have to do the square root on both side x= 289
x= 17
Answer:
x = 4√2 or ≈ 5.66
Step-by-step explanation:
- AB = √5²-3² = √16 = 4
- AB=AC ⇒ BC = AB√2
- x = 4√2 ≈ 5.66
Step-by-step explanation:
Hey there!
Given;
Midpoint is (-1,3) and one endppint is; A(4,-1).
Let the coordinates of C be (x,y).
<u>Use</u><u> </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>formula</u><u>.</u>
<u></u>
<u>Put</u><u> </u><u>all values</u><u>. </u>
<u></u>
Since, they are equal, equating with their corresponding elements we get,
<u>Simplify</u><u> </u><u>it</u><u>. </u>
<u></u>
<u></u>
<u>Again</u><u>,</u>
<u></u>
<u>Simplify</u><u> </u><u>it</u><u>. </u>
<u></u>
<u></u>
<u>Therefore the</u><u> </u><u>another</u><u> </u><u>endpoint is</u><u> </u><u>C</u><u>(</u><u>-6</u><u>,</u><u>7</u><u>)</u><u>.</u>
