Sagot :

Answer:

m<1 = m<2 = 98

Step-by-step 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
