Answer:

x = 374/7

Step-by-step explanation:

all of the angles should equal to 360 degrees since it's a quadrilateral.

So,

1+ (2x+10)+(3x-5)+(2x-20) = 360

1+ 2x+10 +3x-5+2x-20 = 360

7x -14 =360

7x = 360+14

7x = 374

x= 374/7

x= 53.428...

Hope this helps!

Which expression is equivalent to the pic

finlep [7]

Answer:

OPTION A: $\frac{1}{2^{15}}$

Step-by-step explanation:

We should know that:

$(a^b)^c = a^{b . c}$

So, $(2^3)^{-5} = 2^{3 . (-5)}}$

$= 2^{-15}$

This is equivalent to $\frac{1}{2^{15}}$

Hence, OPTION A is the answer.
