Well you will get a right angled triangle
Using Cos x = adj/hyp
cos33.9 = 8.2/hyp
hyp=8.2 / (cos33.9). So it would be <span>9.9 miles to 1 dp</span>

What is liner equation with two variable?
- An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
- For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
-10x² -10y² = -300 ----a
5x² + 5y² = 150 ---- b
While trying to solve this,
We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.
10x² + 10y² = 300 ----c
-10x² -10y² = -300 ---a
<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>

Answer:
- y = x² + 4
- x = √(4-y)
- x² - y = -4

She owes more than $30. She owes for the -$30 that we know of, however much over the -$30 she is, and most likely and interest fee as well.
