Answer:
m<1 = m<2 = 98
Explanation:
the measurement of angle 1 and 2 are the same because the two triangle half's (top and bottom) of the polygon are congruent.
any 4 sided polygon has sums of their internal angles = 360 degrees.
(for example a square has four 90 degrees angles, 360=90+90+90+90)
we know that 2 angles are 90 and 74,
we also know that the 2 other angles (m<1 and m<2) are the same,
m<1 +m<2 +90 +74=360
m<1+m<2=360-90-74
2*m<1=196
m<1=196/2
m<1=98
m<2=98
