The data in the table shows that the speed of a wave is related to both the wavelength and the frequency of the wave. What is a reasonable estimate of the wavelength represented by X in the table?

4 m

5 m

8 m

12 m

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.

Check the internet ok that will

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
