Answer:

x = 140

Step-by-step explanation:

in triangle SNU

angle U is 180-120 = 60

total angle of triangle is 180°

so, 180-80+60 = 40

angle S and angle P is equal because SN and PD are parallel.

so 180-40 = X

X = 140°

btw, i know i already answered this, but yee

The value of x is 140°

Answer:

Solution given;

we have

∡NSU+∡SNU=∡NUP[since exterior angle is equal to the sum of interior angle of a triangle]

∡NSU+80°=120°

∡NSU=120°-80°

∡NSU=40°

again

∡NSU=∡DPA=40°[ being corresponding angle]

again

∡DPA+DPU=180°[ sum of angle of a straight line is 180°]

40°+x=180°

x=180°-40°

x=140°
