Can someone please help me find x​

Mathematics
1 answer:
DIA [1.3K]3 years ago
4 0

Answer:

2\sqrt{5}

Step-by-step explanation:

The picture (attached) shows two isosceles right triangles, so the altitude marked x splits the bottom side in half, 4 units and 4 units.

Each triangle is a right triangle with one leg of length 4, hypotenuse 6. Use the Pythagorean Theorem (leg)^2 + (leg)^2 = (hypotenuse)^2.

4^2+x^2=6^2\\16+x^2=36\\x^2=20\\x=\sqrt{20}\\x=2\sqrt{5}

evablogger [386]
3/4 of $60 = $45 for the coat
60 - 45 = $15 left
1/2 of $15 = $7.50 for the skirt
15 - 7.50 = $7.50 left
