Answer:
27 cm
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2 +b^2 =c^2
a and b are the legs and c is the hypotenuse.We know one of the legs is 13 and the hypotenuse is 30
13^2 + b^2 = 30^2
169 + b^2 = 900
Subtract 169 from each side
169-169 +b^2 = 900-169
b^2 = 731
Take the square root of each side
sqrt(b^2) =sqrt(731)
b = 27.03

Hi, thank you for posting your question here at Brainly.
To find the velocity of light or any electromagnetic wave, we use the equation: v = wavelength * frequency. Substituting,
v = 0.5 m * 930 1/s
v = 465 m/s
