By scale drawing, find the resultant of vectors 70n inclined at100n and direction of the resultant 100n

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
