Question

A,b and c form a triangle where bac = 90 degrees ab = 13mm and ca =9.7mm fond the length of bc guving youre answer rounded to 1 dp

Answer 1

Answer:

Step-by-step explanation:

$h^{2} = p^{2} + b^{2} \\13^{2} = p^{2} + 9.7^{2} \\169 - 94.09 =p^{2} \\74.91 =p^{2}\\p =\sqrt{74.91}\\ p = 8.655\\\\Length of BC rounded to 1 decimal place is 8.7 mm$
