The angles inside a triangle always add up to 180 degrees.
The whole thing is one big triangle made of two smaller ones.
28 + 58 + 77 + x = 180
163 + x = 180
x = 180 - 163
x = 17
Answer:
24%
Step-by-step explanation:
The total amount of guests is 50. 12/50 saw Wonder Woman 1984. To turn that into a percentage you have to divide 12 by 50 which is .24. Therefore, 24% of the guests saw Wonder Woman 1984.
-7x - 6y = 59.....multiply by -1
-8x - 6y = 58
----------------
7x + 6y = -59 (result of multiplying by -1)
-8x - 6y = 58
---------------add
-x = -1
x = 1
-7x - 6y = 59
-7(1) - 6y = 59
-7 - 6y = 59
-6y = 59 + 7
-6y = 66
y = -66/6
y = -11
solution is (1,-11)
