I don’t understand how to get x and y

Mathematics
1 answer:
DIA [1.3K]4 years ago
8 0

Answer:

x is approximately 7.97 or 8.0

y is approximately 6.9

Step-by-step explanation:

We have a triangle:

side a = y

side b = 4

side c = x

We can use the trigonometric function tangent which relates opposite and adjacent sides of the triangle in respect with a certain angle.

In this case we'll be using angle of 60º

y is opposite to 60º and 4 is adjacent

tan=\frac{opposite}{adjacent}

Solve for opposite;

opposite=adjacent*tan\\o=4*tan60\\o=6.9

This is the value of y.

To find x, we can use the pythagorean theorem.

c^2=a^2+b^2\\c=\sqrt{a^2+b^2} \\c=\sqrt{(4)^2+(6.9)^2} \\c=\sqrt{16+47.61}\\ c=\sqrt{63.61}\\ c=7.97

7.97 ≅ 8.0

Answer:

<u><em>Question 1:</em></u>

The smallest 5-digit no. is <u><em>10,000</em></u>

<u>The product of its prime factors is:</u>

=> 10,000 = 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5

<u><em>Question 2:</em></u>

The prime factors of 1729 are:

=> 1729 = 7 × 13 × 19

The relation between their 2 consecutive prime factor is that when they both are subtracted, they give the result 6

<u><em>Such as :</em></u>

=> 13-7 = 6

=> 19-13 = 6
