Question

Please Help Me!! I can’t figure this out!!

Answer 1

a=12 ft, b=12 ft

Explanation:

-Length A and length B are equal since the right angle triangle is also an isosceles triangle.

-We use the Law of sines to calculate the two lengths:

`(a)/(Sin \ A)=(b)/(Sin \ B)=(12√(2))/(Sin\ 90\textdegree)\\\\a=b=12√(2) \ Sin \ 45\textdegree\\\\a=b=12\ ft`

Hence, length a is equal to length b which is equal to 12 ft
