Sin < O = 10/15 = 2/3
so m < O = 41.8 degrees
m < Y = 90 - 41.8 = 48.2 degrees

Answer: choice B) 2 by 6</h3>
===============================================
How I got that answer:
Opposite sides of the rectangle are the same length, so
y = 2x-4 (horizontal sides)
3y = x+3 (vertical sides)
-----------
Start with the second equation. Replace the 'y' with (2x-4) which is from the first equation. This replacement will allow us to solve for y
3y = x+3
3(2x-4) = x+3 .. replaced y with (2x-4)
6x-12 = x+3 ... distribute
6x-12+12 = x+3+12 ..... add 12 to both sides
6x = x+15
6x-x = x+15-x ..... subtract x from both sides
5x = 15
5x/5 = 15/5 ........ divide both sides by 5
x = 3
----------
Now we know the value of x, which means we can find the value of y
y = 2x-4
y = 2*3-4 .... replace x with 3
y = 6-4
y = 2
So the horizontal side is 2 units long
The vertical side is therefore 3y = 3*2 = 6
or we can say x+3 = 3+3 = 6 getting the same answer
The expansion of the given expressions are; 4x² - 5x - 5; 2x² - 13x + 15; -2x² - 5x + 3; 3x² + 6x - 1
<h3>How to simplify Quadratic equations?</h3>
A) x(x - 5) + 3x² - 5
Expanding this gives us;
x² - 5x + 3x² - 5
⇒ 4x² - 5x - 5
B) (2x - 3)(x - 5)
Expanding the function gives;
⇒ (2x² - 3x - 10x + 15)
⇒ 2x² - 13x + 15
C) -2x(x + 3) + x + 3
⇒ -2x² - 6x + x + 3
⇒ -2x² - 5x + 3
D) 3(x + 1)² - 4
⇒ 3(x² + 2x + 1) - 4
⇒ 3x² + 6x + 3 - 4
⇒ 3x² + 6x - 1
