Answer:
Step-by-step explanation:
A, B & C lie on a straight line.
D, C & E lie on a different straight line.
Ah, this is 2 intersecting lines
angles
y
= 106° and angle
z
= 64°.
well we know that a full size of circle is 360 degrees
let's add z and y :
106+64 = 170
then, let's subtract it from 360
360 - 170 = 90
we must devide it by 2, why? because 90 is from two section of x (2x)
so 90/2 = 45
and there you have it x = 45
if you still cannot visualize what is intersecting line mean, then see the file below
We have , so that
, so
, and any solution of the form
satisfies the congruence, where
is any integer.
