If a and b are supplementary and ma = 37°45', then mb = 142°15'. true false

True.

Step-by-step explanation:

37°45' + 142°15'

= (37 + 142)° + (45 + 15)'

= 179° + 60'

= 179° + 1°

= 180°

there being 60 minutes of arc in one degree of arc.

factor trees are nice.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
