Mathematics
1 answer:
skad [1K]3 years ago

Answer:

m<A = 20

Step-by-step explanation:

6y plus 3y = 9y

180 divided by 9 = 20

20x6=120

20x2=40

120+40=160

a triangle is equal to 180 so..

180-160=20

i did 6y + 3y because that line is 180 degrees ( half of a circle)

What is the value of X?<br><br> What is the value of Y?<br><br> What is the value of Z?
baherus [9]

Answer:

The answer is

x = 12 \\ y = 20 \\ z = 15

Step-by-step explanation:

By using Pythagoras low

Then we can find that

{y}^{2}  =  {x}^{2}  +  {16}^{2}  \\  {z}^{2}  =  {x}^{2}   +  {9}^{2} \\  {y}^{2}   +  {z}^{2}  =  {25}^{2} \\  then \\  {x}^{2}  +  {9}^{2}  +  {x}^{2}  +  {16}^{2}  =  {25}^{2}  \\ 2 {x}^{2}  = 288 \\ x = 12 \\ By  \: substituting \:  x \:  into  \: the  \: previous \:  equations \\ then \:  \\ y = 20 \\ z = 15

Rename 5/6 and 14/15 using the least common denominator.
baherus [9]

Answer:

\frac{25}{30}~and~\frac{28}{30}

  • Multiply 5 by 5 to get your first parameter.

5 * 5 = 25

  • Multiply 6 by 5 to get the denominator, or your second parameter.

5 * 6 = 30

  • For the second fraction, \frac{14}{15}, you need to multiply both parameters by 2, similar to before, but we now must use a different number, otherwise, the denominators will not be the same.

14 * 2 = 28

  • Now, multiply 15 by 2

15 * 2 = 30

  • The last step is to put these numbers you gathered into fractions. The bigger number always goes on the bottom, referred to as the denominator, while the smaller number, referred to as the numerator, always goes on the top.

25~and~30 -- > \frac{25}{30}

28~and~30-- > \frac{28}{30}

________________________________________________________

Finally, the problem is solved. Now that the problem is solved, we review what we just learned <em>not through more problems, though.</em>
