Answer:
137
Step-by-step explanation:
First start with what you know. The measure of the interior angles of a triangle total to 
so 51 + 2x + x = 180, then 51 + 3x = 180, 3x = 129, so
x = 43, the exterior angle is on a straight line with x so
x + exterior angle = 180 [since they are supplementary], since x = 43 then
43 + e = 180, so e has to be 137
1g=16c
16g=X
X=256
I really hope that helped
Answer: 8.25
Explanation: You are looking to find something constant or something that stays the same. Something that does stay the same is how much money she earned each hour. So you would do 453.75/55. And then find k, or the constant of proportionality. Which is $8.25. You’re welcome!
If it's a perfect square, then it's easy. However, if it's not a perfect square, use the square root button on your calculator. IF you happen to know calculus then you could use Newton's Method....but I'm thinking you're not there yet. So stick with the calculator.
