Answer:

x = 7

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

\therefore \: (14x + 2) \degree + 80 \degree = 180 \degree  \\  \\  \therefore \: (14x + 2) \degree = 180 \degree   - 80 \degree \\  \\ \therefore \: (14x + 2) \degree = 100 \degree \\  \\ 14x + 2 = 100 \\ 14x = 100 - 2 \\  \\ 14x = 98 \\  \\ x =  \frac{98}{14}  \\  \\ x = 7

What is the answer of 7 copies of the sum of 8/5 + 4
kotykmax [81]
To solve (8/5 + 4)7, you first have to add 8/5+4.  But you cannot simply add the too because they have to be in a common denominator 'form'.  To do that, we find a common denominator which is 5.  We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28.  You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1.  Another of saying 28/5 is 5 3/5.  So 5 3/5 x 7/1= 39 2/10 (final answer)

Kobotan [32]

Answer:

30,40,50

Step-by-step explanation:

If it is a right triangle then the pythagorean theorum would work

a^2+b^2=c^2

30^2+40^2=50^2

900+1600=2500

2500=2500

this means that 30,40,50 is the right answer

*******extra********

also 30,40,50 is a pythagorean triplet

pythagorean triplets form right angles

this one came from the original triplet of 3,4,5---just multiply by 10
