Answer:
angle c is 13 as it said in the question
Step-by-step explanation:
To solve this question, first cross multiply
Let ? = x
4/9 = x/81
4(81) = 9(x)
Simplify.
81 x 4 = 324
324 = 9x
Isolate the x, divide 9 from both sides
324/9 = 9x/9
x = 324/9
x = 36
4/9 = 36/81
36 is your answer
hope this helps!

I think it's this but I'm not sure if I did it right
Hey there! :)
Your answer is: Between 11 and 12

12² = 12 × 12 = 144
129 is between 121 and 144
Hope this helps :)
