Check the picture below.
recall that in a rhombus the diagonals bisect each other at a right-angle, and that all sides are equal.
thus the longer diagonal is 2a long, and the shorter diagonal is 2b long.
4 3/4+2 5/6
=19/4+25/6
=19/4+17/6
=91/12
=7 7/12
Answer:
m2 = 145
m3 = 145
m4 = 35
Step-by-step explanation:
m<1 = m<4 because of vertical angles
m<2 + m<1 = 180
m<2 + 35 = 180
m<2 = 145
m<2 = m<3 because of vertical angles
