Question

Abc is an equilateral triangle .Point p is on base bc such that pc=1\3 bc if ab=6cm find ap

Answer 1

Answer:

5.3

Step-by-step explanation:

assume an equilateral triangle

if base is ab is 6 then bc is also 6, point between bc is 1/3 of bc or 1/3 of 6,

thus it is 2 from p to c..

consider the triangle bap..with the interior angle at b equal to 60 degree

use now the cosine law..in which

line ap^2= 4^2+6^2-2(4)(6)cos60

then ap or the required length is 2square root of 7

or 5.29
