Answer:

Step-by-step explanation:

As x and y are perpendicular - we can use pythagoras.

So, The length of side x squared + The length of side y squared = The missing length squared.

12^2=144

5^2=25

144+25=169

sqrt169=13

Answer:

Unknown side = 13 in

Step-by-step explanation:

If it is a right sided triangle, then you can use the Pythagoras theoreum.

unknown side = u

x² + y² = u²

12² + 5² = u²

u² = 144 + 25

u² = 169

u = + - SQRT(169)

{Only the positive value has a meaning}.

Unknown side = 13 in

Answer:5.8

Step-by-step explanation:

Given

weight of chair with person on it =2118 N

Barber applies a force of 63 N

Using pascal's law

we know pressure around both sides is equal

i.e. $P_{chair}=P_{piston}$

pressure= $\frac{force}{area}$

$P_{chair}$ = $\frac{2118}{\pi \dot r_{plunger}^2}$

$P_{piston}$ = $\frac{63}{\pi \dot r_{piston}^2}$

substituting values

$\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]$ = $\frac{2118}{63}$

$\left [\frac{r_{plunger}}{r_{piston}}\right ]$ = $\left [ \frac{2118}{63}\right ]^{0.5}$

$\left [\frac{r_{plunger}}{r_{piston}}\right ]$ =5.798
