Answer:
−87+33i
Step-by-step explanation:
Answer:
A = 20 degree
B = 160 degree
C = 160 degree
D = 20 degree
Step-by-step explanation:
If the measure of angle C is eight timeseight times the measure of angle A
That means C = 8A
But According to the question, angles A and D have the same measure as well as angles C and B.
That is, B = 8A and D = A
If A + B + C + D = 360
Let us substitute for B, C and D
A + 8A + 8A + A = 360
18A = 360
A = 360/18 = 20
Therefore
A = 20 degree
B = 8 × 20 = 160 degree
C = 8× 20 = 160 degree
D = 20 degree
