Please help me I need it urgently.

Answer 1

Answer:

sum of angles = 540⁰

90⁰ + x⁰ + x⁰ + x⁰ + x⁰ + 10 = 540⁰

4x⁰ = 540⁰ - 100⁰

4x⁰ = 440⁰

x⁰ = 110 ⁰ ( option 1 )

Answer 2

Answer:

Sum of all the interior angles = 540°

Now , To find - " x "

• Add all the angles →

x° + x° + x° + (x + 10)° + 90 = 540°

4x° + 100° = 540°

4x° = 540° - 100°

4x° = 440°

x = 440°/4°

x = 100°

First option is correct = x → 110 degrees .
