Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y =
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4
1/12. There are 12 possibilities, and only one number under 2.
7 ( 5x - 6)
35x - 42 is the answer
.15 x 75.5 = 11.33 ........ this is a 15% tip
11.33 + 75.5 = 86.83
