If m<1 120*, find m<3.

I assume that <1 and <3 are adjacent angles.  Adjacent angles form the total measurement of 180°.  Add 'em altogether and solve for m<3!

m<1 + m<3 = 180°

120° + m<3 = 180°

m<3 = 180° - 120°

Step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
