Answer:

b = 21 ft is the answer.

Step-by-step explanation:

a = 28 ft

b = ?

c = 35 ft

According to the Pythagoras theorem,

a² + b² = c²

28² + b² = 35²

784 + b² = 1225

b² = 1225 - 784

b² = 441

b = 21 ft

∴ b = 21 ft is the length of the missing leg.

IM SORRY BUT I NEED THIS QUESTION TOO ASAP PLEASE
Paraphin [41]

Using proportions, it is found that the amount of the novel she would have read is:

D. 14/15.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:

\frac{5}{6} + \frac{1}{10} = \frac{25 + 3}{30} = \frac{28}{30} = \frac{14}{15}

Hence option D is correct.

The x value does not matter as long as the y value is given as 10. The domain is any real value. The range is 10
