Answer:
in any quadrilateral, the sum of the interior angles is 360 degrees, so angles
a+b+c+d = 360 degrees.
But a = 2b
and b = 2c
and c = 2d so...
b = 4d and
a = 8d so we have:
8d+4d+2d+d = 360
15d = 360 and
d = 24 degrees
c = 2(24) = 48 degrees and
b = 4(24) = 96 degrees and
a = 8(24) = 192 degrees.
Answer:
12

Answer:
Step-by-step explanation:
Tbh Idk
L = S + 80
180 - L - S = S + 10 simplify: L = 180 - 2S - 10
L = 170 - 2S = S + 80
3S = 90
S = 30 L = 110 3rd angle = 40
