Answer:
Measure of angle A = 55°.
Step-by-step explanation:
From the picture attached,
2 = 2
Corresponding sides of the given triangles ΔACB and ΔNLM are proportional.
Therefore, ΔACB ~ ΔNLM.
m∠A = 180° - (90° + 35°) [By triangle sum theorem]
= 180° - 125°
= 55°
Measure of angle A is 55°.
Answer: (5, -2)
Step-by-step explanation:
Substitute x-7 for y in 2nd equation
Solve for y
This would actually be a very broad question. So, when considering these kinds of questions, one thing that we would really want to consider would be the 
value in this case. We would want to find the amount, and also the terms of the expression.
So, let's suppose that the amount would be 200.
And let's say that Shauna makes 5 a week.
Then the expression would then look like
I hope this would help you in your case of the problem! :)
