Answer:
1.84ft
Step-by-step explanation:
From the figure attached,
AB = Height of the window = 15ft
Let the distance between the base of the housr and the fence 'C' = xft
If the angle of depression = 7°
Then angle of elevation of the top of the fence from the house = 7°
Now from right triangle ABC,
tan7° = x/15
x = tan7°×15
x = 0.1227×15
x = 1.84ft
Therefore, distance of the house from the fence is 1.84ft
Answer:
pg. 1
teresa: use difference of 2 squares
rico: 6561 is not a perfect square
pg. 2
i think teresa is right and that 6561 can be broken down
problem 1: (x^4-81)^2=(x^2-9)^4=(x-3)^8
problem 2: a. false b. rico
pg. 3
problem 3: a. -1(3x+5)^2 b. teresa is right because it cant still be a perfect square trinomial while having a negative first term.
problem 4: a. (y+3)^2 b. teresa
pg. 4
problem 5: a. (x^n+y^n)(x^n-y^n) b. teresa
teresa got more right, rico is buying pizza
Step-by-step explanation:
apex
The composite figure is made up of 2 rectangles.
Area of the top rectangle = 9 x 10 = 90 m²
Area of the bottom rectangle = 30 x 9 = 270 m²
Area of the figure = 90 + 270 = 360m²
Answer: Area = 360m²
My Mom did the work. The answer came out as X= 4.
