Answer:
d = 90°
e = 147°
f = 33°
Step-by-step explanation:
Answer: -0.053
Step-by-step explanation:
1•(18/38) + -1 •(20/18) = -0.053
The answer is 0 < x <span>≤ 7
</span>
First, we know that width = x
Which means that length = x +18
So, the possible equation for the Table's area is
X (X + 18) ≤ 175
X^2 + 18x - 175 <span>≤ </span>0
Next, we need to calculate is by using complete square method
x^2 + 18x + 81 <span>≤ 175 + 81
(x + 9)^2 </span><span>≤ 256
|x + 9| </span><span>≤ sqrt(256)
|x + 9| </span><span>≤ +-16
-16 </span>≤ x + 9 <span>≤ 16
</span>-16 - 9 ≤ x <span>≤ 16 - 9
</span>-25 ≤ x <span>≤ 7
Since the width couldn't be negative, we can change -25 with 0,
so it become
</span> 0 < x ≤ 7
The total area of the blades is the area of a triangle multiplied by 4.
We have then:
Where,
b: base of the blades
h: height of the blades
Substituting values we have:
Doing the calculation we have that the area of the blades is given by:
Answer:
The total area of the blades is:
