Question

Find x in following figure​

Answer 1

Answer:

X=130°

Step-by-step explanation:

So, In the pictures

1. I made line AB that bisect ∠100°

2. After bisecting  ∠100° , two angles will be formed, one will be above the line AB and the other will be below, both of them will be of measure 50°(because AB is a bisector, it divides(bisects) into half)

3. Suppose the angle above the line AB is called y

4. Suppose the angle next to x is Z

5. Angle Y and Z are corresponding angles, so they are equal, which means angle Z will equal 50° like angle y

6. Angle Z and X are both on a straight line, meaning that their sum should be 180 (straight angle)

7. So, from 6. we conculed that ∠X° = 180 - ∠Z°

∠X° = 180 - 50

∠X° = 130°
