Firdaus measured the length of the wall and got 9 feet her cousin measured the same distance and said that it was three what unit was her cousin used to measure how do you know

Her cousin used Yard  to measure the wall.

Step-by-step explanation:

Firdaus measured the length of the wall and got 9 feet.

Her cousin measured the same distance and said that it was 3.

To find the answer, we have to use division.

Let "x" the divisor which divide 9 and gives the answer 3.

9 ÷ x = 3

3x = 9

To find x (divisor) we need to divide both sides by 3, we get

3x ÷ 3 = 9 ÷ 3

x = 3

So  1 unit cousin's measure = 3 feet Firdaus measure

We know that 1 yard = 3 feet.

Therefore, her cousin used Yard measure to measure the wall.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
