Answer:
10
Step-by-step explanation:
Using trigonometry :
Taking the angle 45°
From trigonometry :
Sin θ = opposite / hypotenus
Opposite = s ; hypotenus = 10√2
Sin 45 = s / 10√2
Recall :
Sin 45 = 1/√2
We have ;
1/√2 = s / 10√2
s = 10√2 * 1/√2
s = 10√2 / √2
s = 10

Step-by-step explanation:
To do this there are many steps
Step 1: Turn the whole bathroom into a regular rectangle, so a 7.5x9.5 size bathroom or 71.25 sq ft.
Step 2: Figure out the area of the missing spaces
To do this you need to figure out the side lengths, so for the right tall side, its 7.5 and for the left its 6.5, there is a 4 and a 3, you take that and you can figure out the first spot in pink is .5x4=0.20 then the second one, you find the side length difference and thats the height (1) and then you know the width is 5 so 5x1=5 add those, 5+0.20= 5.20 and subtract that value from 71.25 to get her actual value, 66.05
I hope this helps, when i was writing the steps i decided it would be easier to write on the shape, so i am attaching that, I hope i helped you (:
Answer:
<em>R</em><em>=</em> {-7,-2}
Step-by-step explanation:
- divide 14 into 2 and 7 because 2x7=14
- write the equation as a multiplication of (x+7) and(x+2) =0
- for the result to equal zero. at least one of the factors must equal zero, therefore we get two solutions
