The following problem refers to strings in A, B, ..., Z.
pshichka [43]

Answer:  676

Step-by-step explanation:

The total number of letters in English alphabet {From A to Z} = 26

We assume that the repetition of letters is allowed.

If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-

1\times26\times26=676

Hence, the number of ways to make three-letter strings that begin with H is 676.

What is the answer lol somebody help me please and thank you !
PilotLPTM [1.2K]

I'm guessing that you know about 45-45-90 and 30-60-90 triangles.

In 45-45-90 triangles, the legs are in a ratio such that the hypotenuse is \sqrt{2} times the legs.

In 30-60-90 triangles, the legs are in a ratio of 1:\sqrt{3}:2

In the picture given we have been given a value of the side of the 45-45-90 triangle. We can deduce that the value of the hypotenuse is 9\sqrt{2} because of the ratio of the sides of a 45-45-90 triangle.

The 30-60-90 triangle shares the same hypotenuse, and so we now know a value of one of its sides as well. The ratio of the side of value 'x' and the hypotenuse is \sqrt{3} : 2

We can create an equation to solve for x using these ratios:

\frac{\sqrt{3} }{2} = \frac{x}{9\sqrt{2} }

Cross multiply:

2x = 9\sqrt{6}

x = \frac{9\sqrt{6} }{2}
