Answer: 2,72 and 72, 2
Step-by-step explanation:
Use the law of sines
11/sin50°=13/sinθ
11/0.766=13/sinθ
11sinθ=13(0.766)
11sinθ=9.958
sinθ=9.958/11
sinθ=0.9052727
use arcsin on your calculator
θ=64.86°
Answer:
A=670
B=301,600
C=560
Step-by-step explanation:
A is K divided by the wavelength (m) 301,500 / 450
B is wavelength(m) multiplied by the Frequency (Thz) 520x580
C is K divided by the Frenquency (Thz) 302400 / 540
