LOTS OF POINTS, WILL GIVE BRAINLIEST!!!

Answer 1

• ➡30 is correct answer
• ➡option b is correct

$\large\huge\green{\sf{Answer:-}}$

since we know on straight line 180° is formed

then

➡90° +(x+x+x)= 180°

➡90° + 3x = 180°

➡3x= 180°-90°

➡3x= 90°

➡x = 90°/3= 30°

➡x= 30°

then in triangle sum of all angles = 180°

➡90°+x+y = 180°

➡90°+ 30° +y = 180°

➡120+y = 180°

➡y= 180°-120°

y = 60

• now to find y-x = 60°-30°=30

➡30 is correct answer

➡option b is correct
