Question

please solve this 4 sum tomorrow is my test ​

Answer 1

Answer:

We know that AngleB and Angle S are opposite angles so , AngleS= 100°

We know that AngleS and Angle E are alternate angles so, 180°-100°=80°

Angle E (z)=80°

We know that (y) and (z) are linear pairs so, 180°-80°=100°

Hope it will help you and Mark it as brainlist and follow me on brainly I will follow you back plz...

Answer 2

Answer:

Step-by-step explanation:

Since it is a parallelogram opposite angels are equal therefore angle B= angleS (which is x)

Therefore x = 100 degree

In a parallelogram the CO interior angles( in the given triangle they are angle S and angle z) have a sum of 180 degrees

Therefore we will write angle z + angle x = 180

Z+ 100 = 180. ( x = 100 proved)

Z= 80 degrees

Now, z+y=180 ( linear pair)

80 + y = 180

Y = 100 degrees

X=100, y = 100, Z = 80

Hope this clears everything!

All the best
