Find the missing side lengths

AURORKA [14]

Answer:

X = 18

Y = 9√3

Step-by-step explanation:

use sin equation for right angle triangle

The sine of the angle

= ( the length of the opposite side ÷ the length of the hypotenuse.)

according to this question,

sin 30 = 9 / X

1/2 = 9 / X

X = 18

use cosine to find y

The cosine of the angle

= (the length of the adjacent side ÷ the length of the hypotenuse.)

cos 30 = y/x

√3/2 = y/ 18

y = 9 ✓3

The combined land area of the countries A and B is 159159,973 square kilometers. Country A is larger by 473473 square kilometer

lora16 [44]

Answer:

The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively

Step-by-step explanation:

Let the area of Country B be x

We are given that Country A is larger by 473 square kilometers.

Area of Country A = x+473

Total area of both countries = x+x+473

Total area of both countries = 2x+473

We are given that The combined land area of the countries A and B is 159,973 square kilometers.

So, $2x+473=159973$

$2x=159973-473$

$x=\frac{159973-473}{2}$

x=79750

Area of Country A = x+473=79750+473=80223 sq.km.

Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
