Answer:

I'm not sure if you can solve this with Pythagorean Theorem because as far as I know, you need sides not angle+side combination. Despite this, let's solve this one using sine law, cosine law or even tangent.

Step-by-step explanation:

$\tan(61) = \frac{length \: of \: df}{24} \\ length \: of \: df = 24 \tan(61) \\ = 43.2971 \\ \\ \cos(19) = \frac{length \: of \: df}{length \: of \: ef} \\ length \: of \: ef \: = \frac{43.2971}{ \cos(19) } \\ = 45.7919$

A rectangular lamina of uniform density is situated with opposite corners at (0,0) and (15,4). calculate its radii of gyration a

Sphinxa [80]

First, you have to find the moment of inertia along the x and y axes. Constant density is denoted as k.

$I_{x}= \int\limits^15_0\int\limits^4_0 {k y^{2} } \, dx dy= \frac{1}{3}k (15-4)^4=4880.33k$

$I_{y}= \int\limits^15_0\int\limits^4_0 {k x^{2} } \, dx dy= \frac{1}{3}k (15-4)^4=4880.33k$

Then, the radii of gyration for

x = √[I_x/m]
y = [I_y/m]

where m = k(15-4)² = 121k. Then,

x = y = [4880.33k/121k] = 40.33

I hope I was able to help you. Have a good day.
