The value root of 40 of lies between which two consecutive integers

1 answer:

4 0

When you square +6 or -6 you get 36. That's less than 40.

When you square +7 or -7, you get 49. That's more than 40.

So one of the square roots of 40 is between +6 and +7, and
the other square root of 40 is between -7 and -6 .

Help please!!!! x = ___ units

Natali [406]

Answer:

x = 20 units

Step-by-step explanation:

∆KJL is a 30° - 60° - 90° triangle which means that side opposite of 30° is x, side opposite of 60° is x√3, and side opposite of 90° is 2x.

Since side opposite of 90° is 40√2 which is 2x and x is the side opposite of 30° (JL).

2x = 40√2 → 2x ÷ 2 = 40√2 ÷ 2 → x = 20√2.

∆JML is a 45° - 45° - 90° triangle which means that sides opposite of 45° are x and 90° is x√2.

Since side JL is also the side opposite of 90° and the sides opposite of 45° are the value x,

20√2 = x√2 → 20√2 ÷ √2 = x√2 ÷ √2 → 20 = x →

x = 20.
