Answer:

z = 16°

Step-by-step explanation:

The sum of angles in a triangle is 180°

∠1 + ∠2 + ∠3 = 180°

(z + 29°) + 55° + 5z = 180°

Collect like terms;

6z + 84° = 180°

Subtract 84° from both sides;

6z = 96°

Divide both sides by 6;

z = 16°

Answer:

w = 1.6

Step-by-step explanation:

Given w varies inversely as $\sqrt{x}$ then the equation relating them is

w = $\frac{k}{\sqrt{x} }$ ← k is the constant of variation

To find k use the condition when x = 4, w = 4

k = w $\sqrt{x}$ = 4 × $\sqrt{4}$ = 4 × 2 = 8

w = $\frac{8}{\sqrt{x} }$ ← equation of variation

When x = 25, then

w = $\frac{8}{\sqrt{25} }$ = $\frac{8}{5}$ = 1.6
