3 times the measure of an angle is 14 less than the measure of its complement. What is the measure of the angle? 19° 57° 71° 76°

liberstina [14]

Answer:

x = 19°

Step-by-step explanation:

Let The angle be "a"

Now according to the question,

⇒ 3 × a = (90° - a) - 14° (Then remove the brackets)

⇒ 3a = 90° - a - 14°

⇒ 3 + a = 76°

⇒ 40° = 76°

⇒ a = 76/4

Now since you got 76/4 you have to make it into simplest form so it'll be :

19/1

Your answer is : a = 19°

What is the LCD of 5/12 and -9/16 ?

Andreyy89

The least common denominator of 5/12 and -9/16

The answer is 48.

Now, we have to change the numerators also to make this a equal fraction to the first ones we had.

5*4 = 20
12*4 = 48

20/48

-9*3 = -27
16*3 = 48

-27/48

What is the approximate circumference of the circle shown below?

iVinArrow [24]

If we know the value of r (radius) we can find the circumference of circle using formula $Circumference=2\pi r$

Step-by-step explanation:

We need to find the circumference of circle.

Since the picture is missing in the given question so I will explain the method to find the circumference of circle.

You can use this method to find circumference of the given question.

The formula used to find circumference of the circle is

$Circumference=2\pi r$

Where π is pie and its value is 3.14

and r is radius of circle

So, if we know the value of r (radius) we can find the circumference of circle using formula $Circumference=2\pi r$

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
