Answer:
6
Step-by-step explanation:
You know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)
because you are finding the angle you would go Tan^-1(12÷20) =31°
it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20
Your answer is 31°
Ok since it’s a 45 45 90 right triangle then both sides equal 5. And to find x you do
A^2 +b^2=c^2
5^2 +5^2= c^2
25+25=c^2
50=c^2
Take the square root of both sides and you get X= 5 square root of 2 or 7.071(rounded)
