Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5

Use the point-slope formula:
y-(-5) = (1/2)*(x -(-8)), or y+5 = (1/2)(x+8) is the equation satisfied by
m = (1/2) and the point (-8, -5).
You could eliminate the fraction 1/2 here, or you could rewrite this equation in the slope-intercept form, etc. Your choice!
