@dan815 Yes

9. dan815

then use pythagorean theorm the most beautiful theorm of mathematics until further notice

heres a tip, when you have atleast 3 pieces of information about a triangle its solvable, here u can solve because u know there a 90 degree angle and u know the length of 2 sides

11. dan815

when u have less than 3 pieces of information, u cant really solve it
