Help me on this??? Will mark as Brainiest

11 and 12 is g and g and answer 13 is 5.36487494991

Step-by-step explanation:

first answer is 7 square root 2, second is 39, third is 5.36487494991.

Step-by-step explanation:

1st its a right triangle with both sides as 45 degrees no shorter legs or longer legs. so both opp and adj legs are equal to 7. 7 times 7 plus 7 times 7 is 98 so square it into radical form and get 7 square root 2. second is 39 because of the 3,4,5. 15 36 and 39 are ratios of the rule. Third is 5.45454545... because make a triangle with a right triangle properties. name the hyp variable A. Find each angle which is 90, 56 ( the top of the triangle where plane is ) and 34 ( at the boat place ). You use Sine with 34 which is (0.55919290347...). This is equal to 3 km over A. Change the form and turn it into A=3 divided by 0.55...) which is 5.36487494991.
