Hello!
To find the area of the trapezoid, you use the formula A=1/2h(a+b), where a and b represent the two base lengths.
Since we already know the two bases and the height, we can just plug them into the equation to find the area.
A=1/2·15.4(26.7+9.9)
A=1/2·15.4(36.6)
A=1/2·563.64
A=281.82
The area is 281.82 ft².
I hope this helps!
Answer:
The height of the tower is 2250 meters
Step-by-step explanation:
let's say that when the angle of elevation is x°, the distance to the base of the tower is 'd'. So when the angle of elevation is y°, the distance is d+150.
The tangent of the angle of elevation is the height of the tower (opposite side) over the horizontal distance to the tower (adjacent side).
Then we have that:
angle of elevation x°:
angle of elevation y°:
The exact answer is 2,165.846153846154
Hope this helpssss :)
The remaining balances in the first and second account are $5805 and $1020 respectively.
<em><u>Explanation</u></em>
Suppose, the initial balance in the first account was dollar.
As the total amount in two accounts was $9000, so the <u>initial balance in the second account was</u>
He withdrew 10% from the first and 60% from the second account to buy the ring which cost $2175. So, the equation will be......
So, <u>the initial balance</u> in the first account was $6450 and in the second account was ($9000 - $6450)= $2550
Thus, the remaining balance in the first account = 90% of $6450 =
and the remaining balance in the second account = 40% of $2550 =
