Draw triange ABC Find the length of the missing sides given

Draw triange ABC. Find the length of the missing sides given the following.

1) tanA= 5/12

2) sinB=1/2, a=20

Solution

1. tan A=5/12

tan A=opposite/adjacent

Therefore opposite=5 and adjacent=12

hypotenuse=sqrt(opposite²+adjacent²)=sqrt(25+144)=13
