Answer:
D. 161°
Step-by-step explanation:
m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram
to find x:
4x-17=3x-8
x-17=-8
x=9
m<4=3(9)-8=19
so, m<4=19°
m<2 =19°
to find m<1:
the interior angles of a parallelogram add up to 360°
360-2(19)=2x
2x=360-38
2x=322
x=161°
m<1=161°
Answer:
138.8 cm
Step-by-step explanation:
Angle I =180 - 89 - 38 = 53
Using sine law
i/sinI = k/sinK
180/sin53 = k/sin38
k = 138.76
