From the figure,
(19x+3) =( 11x-2) + (9x+1)______{ exterior angle of a triangle is equal
to the sum of 2 opposite interior angles}
now,
19x+3 = 11x-2 + 9x+1
19x-20x = -2+1-3
-x = - 4
therefore,
X = 4.
if you want to find the value of angles ,
just put 4 Inthe place of X.

Answer:
c = 31.5
Step-by-step explanation:
Given c varies directly as
then the equation relating them is
c = k
← k is the constant of variation
To find k use the condition c = 14 when d = 64, then
14 = k ×
= 8k ( divide both sides by 8 )
1.75 = k
c = 1.75
← equation of variation
When d = 324 , then
c = 1.75 ×
= 1.75 × 18 = 31.5
