Answer:
103
Step-by-step explanation:
Interior angles of a pentagon add up to 540
117+100+105+115+x=540
437+x=540
Subtract 437 from both sides
x=103
Answer: The measure of x is 103°
Step-by-step explanation: A pentagram's angles all together should equal 540, so we can work backwards!
105 + 117 + 100 + 115 = 437
540 - 437 = 103
Hope this helps!
