aivan3 [116]3 years ago
8 0

Answer:

40

Step-by-step explanation:

Using the method of prime factors

8 = 2 × 2 × 2 = 2³

2 = 2

5 = 5

Then LCM = 2³ × 5 = 8 × 5 = 40

Answer:

40

Step-by-step explanation:

The goal of LCM is to get the least common number that can divide any of the numbers given without turning them into fractions until all of them are divided to 1.

The least number that can divide any of the numbers is 2, dividing through we remain with 8/2=4, 2/2=1, and 5. Notice how the 5 remains the same, since dividing it by 2 will turn it into a fraction

Divide through by 2 again, we get 4/2=2, 1, and 5

Divide through by 2 yet again, we get 2/2=1, 1, and 5

Divide through by 5, we get 1, 1, and 1

The LCM is now multiplications of all the least numbers used above= 2*2*2*5=40

Find the values of x,y,z. This diagram is not a scale.
Serjik [45]

Important:
                             The sum of the three angles inside
                              every triangle is always 180°.


First, look at the left triangle alone.
Two of its angles are 46° and 58° .  (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'. 
                                                         x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But  x = 76°.
So z = (180° - 76°).              z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and  z = 104°. 
(13° + 104°) = 117° . 
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
                                                 y = 63° .
