Answer:

425

Step-by-step explanation:

By right angle triangle with sides 20 5

we can find hypotenuse

hyp^2 = 20^2 + 5^2

= 400 + 25

= sqrt(425)

then for all sides it is same length

Area of shaded region = side^2

In parallelogram BCDE if m C<br> B<br> 70<br> 50°<br> E
mr_godi [17]

Answer:

x=130

Step-by-step explanation:

Opposite angles of a parallelogram are equal

EBC = 50° while, CDE = 50° too

Area of a parallelogram is 360°

Suppose, BCD to be x too, & form an equation:

50+50+x+x=360

100+2x=360

2x=360-100

2x=260

x=260/2

x=130

{CHECK: 130+130+50+50=360^{o}}

20 less than12 times a number is 64, what is the number
Genrish500 [490]

20  <  12  ⋅  <em>x</em>  =  64

This is somewhat of a false equation though, due to  the left side  "20"  is not less than the right side  "12 ", which means that the given statement is false.

So I switched it up and made the variable "12"

<u>12  <  20  ⋅  </u><u><em>x</em></u><u>  =  64 </u>

12x - 20 = 64

12x = 64 + 20

12x = 84

12x⁄12 = 84⁄12  

x = 7

I hope this helps, as always. I wish you the best of luck and have a nice day, friend..
