2 + (3 + 4) = (2 + 3) + 4 ⇒2+7 = 5+4.
Step-by-step explanation:
the answer is 3 ft because since the two triangles are diagonal to eachother (i forgot the word) they have the same side length ratio. the ratio of the bigger triangle is 10:6.

Answer:
21.001 cm
Step-by-step explanation:
The diagram shows right triangle with
Hypotenuse ZY = 22.3 cm
Leg XY = 7.5 cm
By the Pythagorean theorem,
![XY^2+XZ^2=ZY^2\\ \\7.5^2+XZ^2=22.3^2\\ \\XZ^2=22.3^2-7.5^2\\ \\XZ^2=(22.3-7.5)(22.3+7.5)\\ \\XZ^2=14.8\cdot 29.8\\ \\XZ^2=441.04\\ \\XZ=\sqrt{441.04}\approx 21.001\ cm](https://tex.z-dn.net/?f=XY%5E2%2BXZ%5E2%3DZY%5E2%5C%5C%20%5C%5C7.5%5E2%2BXZ%5E2%3D22.3%5E2%5C%5C%20%5C%5CXZ%5E2%3D22.3%5E2-7.5%5E2%5C%5C%20%5C%5CXZ%5E2%3D%2822.3-7.5%29%2822.3%2B7.5%29%5C%5C%20%5C%5CXZ%5E2%3D14.8%5Ccdot%2029.8%5C%5C%20%5C%5CXZ%5E2%3D441.04%5C%5C%20%5C%5CXZ%3D%5Csqrt%7B441.04%7D%5Capprox%2021.001%5C%20cm)
