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:
Angle X is 122°
Step-by-step explanation:
Because it's a 180° line (supplementary angle thm):
180°-58°=122°

That leaves
144-138.75 = 5.25 inches for spaces.
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches
= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>
