Answer:
Number 3 is correct.
129.19m
Step-by-step explanation:
You might be wondering how did I got 32⁰, well, that's because they are alternate angles.
Now, we're trying to find the opposite side of the triangle.
Using the laws,
we got cos32⁰=x/243.8
243.8cos32⁰=x
129.19⁰

The perimeter of the entire rectangle is 12 cm.
Answer:
<h2>
m = -¹¹/₄</h2>
Step-by-step explanation:
The equation of a line with slope of <em>m</em> and y-intercept of <em>b</em> is: y = mx + b
b = 2 and line contains the point (4, -9), so:
-9 = m×4 + 2 {subtract 2 from both sides}
-11 = 4m {divide booth sides by 4
m = -¹¹/₄
-3 1/2 = 1/2x + 1/2x + x
- 7/2 = 2x
(-7/2) / 2 = x
-7/2 * 1/2 = x
- 7/4 (or - 1 3/4) = x
