hint:

tan(B) = 24/7

use a calculator to use the arctangent or inverse tangent function to isolate B

jim_thompson5910 · Answer

let me know if that hint helps or not

jim_thompson5910 · Answer

tan(angle) = opposite/adjacent tan(B) = AC/BC tan(B) = 24/7 arctan( tan(B) ) = arctan( 24/7 ) B = arctan( 24/7 ) B = 73.7397953 degrees ... see note below B = 73.7 degrees Note: I used a calculator to evaluate arctan( 24/7 ) to get 73.739795 You can use google as a calculator and type in " arctan( 24/7 ) in degrees" without quotes into google to get this page https://www.google.com/search?q=arctan%28+24%2F7+%29+in+degrees&ie=UTF-8
