Is a triangle with sides of length 6ft, 21 ft, 23 ft. A right triangle?

gayaneshka [121]

Answer:

Step-by-step explanation:

By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.

Thus, $a^{2}+b^{2}=c^{2}$ where where a and b are the legs and c is the hypotenuse.

Let a=6ft, b=21ft and c=23ft, then

$a^{2}+b^{2}=c^{2}$

$(6)^{2}+(21)^{2}=(23)^{2}$

$36+441=(23)^{2}$

$477=529$

which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.

For each 11 mm of coloured fabric June uses to make her curtains, she also uses 1 cm of white fabric. Express the amount of whit

avanturin [10]

Answer: The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$

Step-by-step explanation:

Given :

Amount of coloured fabric used by June = 11 mm = 1.1 cm (1 mm=0.1 cm)

Amount of white fabric used by June = 1 cm

To find : amount of white fabric to coloured fabric as a ratio in its simplest form

To find the ratio in simplest form , the units of both measurements should be same

Thus $\frac{\text {amount of white fabric}}{\text {amount of coloured fabric}}=\frac{1cm}{1.1cm}=\frac{10}{11}$

The amount of white fabric to coloured fabric as a ratio in its simplest form is $\frac{10}{11}$
