Step-by-step explanation:
Mean= sum of all the terms/no. of terms
=12.5+38.3+16.3+2+145+8.5/6
=222.6/6
=37.1
Step-by-step explanation:
The exterior angle is the sum of the opposite interior angles of the triangle.
Therefore, m<D +m<C = 118°
=> 8y+3 +3y+5 = 118°
=> 11y = 118° - 8°
=> 11 y = 110°
=> y = 10°
m<D = 8y+3
= 8(10)+3 = 83°
m<C= 3(10)+5 = 35°
m<DEC = 180° -118° = 62°
