Step-by-step explanation:
G i v e n t h a t t h e t o t a l i n t e r i o r a n g l e s i n p e n t a g o n i s 5 4 0 ° . T h e n y o u a d d u p a l l t h e i n t e r i o r a n g l e s t o g e t h e r i n t e r m o f x :
x+10°+x+20°+x+40°+x+30°+x = 540°
5x + 100° = 540°
N o w , y o u c a n f i n d t h e v a l u e o f x :
5x + 100° = 540°
5x = 540° - 100°
5x = 440°
x = 440°/5
= 88
Answer:
D. 88
Step-by-step explanation:
if you add the given numbers up (equals 100) them subtract it from 540(the degrees of a Pentagon) you get 440. then divide that by 5 (number of xs left) you get 88. You can plug in 88 for x and check but I already did, I hope this helps you lemme know if it does :)
