Find the value of x to the nearest tenth. tan 34° = 20

Likurg_2 [28]

Answer:

The value of x = 13.5.

Step-by-step explanation:

In this question x is missing.

So, the question would be:

tan 34° = x/20.

Now, to find the value of $x$ :

$tan 34 = \frac{x}{20}$

$\frac{x}{20} = tan 34$

Multiplying both sides by 20 we get:

$x=tan 34\times 20$

On simplifying both sides we get:

$x=13.49$

So, to get the value of $x=13.49$ to nearest tenth is 13.5. As we see in hundredth place it is 9 and 4 in tenth place, so after rounding to tenth place 4 will change to 5 so the value is 13.5.

Therefore, the value of x = 13.5.

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? square root of 8 units 4 units squa

ycow [4]

By the Pythagoras theorem, in a right triangle with the sides being a and b,

a² + b² = Hypotenuse²

Hypotenuse² = 4² + 4²

Hypotenuse² = 16 + 16 = 2*16

Hypotenuse = √2 * √16

Thus, hypotenuse = 4√2

What is the measure of angle x? m<x = ?

Ainat [17]

Hey there! :)

The total measure for triangles is 180°

You already know 2 angles. Add both angles and subtract from 180 to find x

37 + 82 = 119

180 - 119 = 61

m∠x = 61°

Hope this helps :)
