Question

Find the fifth angle of a regular pentagon if four angles are 102 , 88 , 168 and 100​

Answer 1

Answer:

we know that,

sum of angles of a Pentagon = 540 degrees

therefore, (100 + 175 + 85 + 75 + x) degrees = 540 degrees

here, x is the fifth angle which we have to find

435 + x =540 degree

x = 540 - 435

x = 105 degrees

Answer 2

Answer:

The fifth angle is 105

Step-by-step explanation:

as the sum of angles are 540

so the fifth angle is 105 degrees
