Four interior angles of a pentagon measure 88°, 118°, 132°, and 100°. what is the measure of the fifth interior angle?
82°
92°
102°
112°

its     102

Step-by-step explanation:

Hello mate!

In a pentagon, we know that the addition of al the angles should be equal to 540°

the angles that we have are 88°, 118°, 132°, and 100°, and their addition is equal to:

88° + 118° + 132° + 100° = 438°

now the missing angle plus 438° should be equal to 540°

A + 438° = 540°

and we need to should it for A.

A = 540° - 438° = 102°

the fifth angle is equal to 102°
