the sum of inner angles = 180°
∠BAO + ∠AOB + ∠ABO = 180°
2x + 1 + 90 + 2x + 5 = 180°
4x + 96 = 180

A person needs to pay TK. 500 to by pencils and TK. X for any additinal unit of pencil.If the cumstomer pays a total of TK. 4700
sp2606 [1]

Answer:

3.50

Step-by-step explanation:

First we take the 500 fee for purchasing pencils off of the total:

4700-500 = 4200

This means we pay 4200 for 1200 pencils; dividing this will tell us the amount per pencil, x:

4200/1200 = 42/12 = 21/6 = 7/2 = 3.5

Thus we pay 3.50 per pencil.

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft sqaured. The area of the triangle is
NeTakaya

Answer:

The length of each side of square is <u>5ft</u>.

Step-by-step explanation:

Given:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.

Now, to find the length of each side of square.

Now, we need to get the area of the square first:

<u>Area of combined figure - area of triangle = area of square.</u>

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

25 =a^{2}

<em>Using square root both sides we get:</em>

5=a

<em>So, the side = 5 ft.</em>

Therefore, the length of each side of square is 5ft.
