1 answer:
Pavlova-9 [17]3 years ago

Answer:

The value of x is 9.

The value of y is 18.

Step-by-step explanation:

The given triangle is a right angled triangle.

We have: $ tan(x) = \frac{opp}{adj} $

Therefore, $ tan(30)  =  \frac{x}{9\sqrt{3}} $

Since, $ tan(30) = \frac{1}{\sqrt{3}} $

Therefore, we have:

$ \frac{1}{\sqrt{3}} = \frac{x}{9\sqrt{3}} $

$ \implies x = 9 $

Now, 'y' is the hypotenuse.

Use Pythagoras theorem, we have $ x^2 + (9\sqrt{3}})^2 = y^2 $

Substituting x = 9, we get:

81 + 81(3) = y²

$ \implies y^2 = 81 + 243 $

$ \implies y^2 = 324 $

$ \therefore y = 18 $

Hence, the value of y = 18.

Find the difference. (12m + 1) - (5m - 4)
Law Incorporation [45]

Answer:

7m + 5

Step-by-step explanation:

1) Simplify.

(12m + 1) - 1 (5m - 4) -> (12m + 1) - 5m + 4

2) Eliminate unnecessary parenthesis.

(12m + 1) - 5m + 4 -> 12m + 1 - 5m + 4.

3) Combine like terms.

12m - 5m = 7m, 4 + 1 =5 -> 7m + 5

The solution is 7m + 5

What percent was a television set reduced if it was marked $225 and sold for <br> $195?
lord [1]
Start off by finding how much the price was reduced. 225-195=30, so it was reduced by $30. This can be put into fraction form as 30/225. Now simply divide that to get about 0.1333, or about 13% when rounded to the nearest whole percentage.
