4 0

Step-by-step explanation:

Let the angle of triangle be x , so each angle will be 1x , 2x , 3x respectively.

We know that sum of all angles in triangle is 180°

So ,

1x + 2x + 3x = 180°

6x = 180°

x = 30°

Therefore , each angle would be 30° , 60° , 90° respectively.

3 There are 5 times as many boys as girls in a school.

Dafna1 [17]

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810 Eqn 1

y = 5x Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

$\frac{6x}{6}=\frac{810}{6}\\x=135$

Putting x=135 in Eqn 2

y = 5(135)

y = 675

Hence,

Number of boys = 675

enot [183]

Answer: The LCM of 8, 9, and 19 is 1,368.

Prime factorization of the numbers:

8 = 2 x 2 x 2

9 = 3 x 3

19 = 19

2 x 2 x 2 x 3 x 3 x 19 = 1,368.

Hope this helps! Have a great day!
