Which atoms move around the most I’m sorry I think it’s gas but I don’t know ( this is for a matter assignment in science)

If x + 10 = 70, what is x? a. 40 b. 50 c. 60 d. 70 e. 80

1. are the corresponding angles congruent 2. find the ratios of the corresponding sides 3. is triangle jkl congruent to triangle rst? if so what is the scale factor

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
