Can someone please help me with this math problem?? It’s Special Right Triangles: Decimal Answers ! Round to the nearest tenth. I will really appreciate it thank you !

Answer:
c = 1.4
d = 8
Step-by-step explanation:
In a 45-45-90 triangle, the legs are equal and the hypotenuse is √2 times that.
2 = c √2
c = 2 / √2
c = 1.4
In a 30-60-90 triangle, the hypotenuse is 2 times the short side, and the long side is √3 times the short side.
d = 2 × 4
d = 8
