Construct a truth table for the logical operator nand.

Answer with Step-by-step explanation:

We are given that NAND

We have to construct the truth table for the logical operator NAND

AND =

NAND==Opposite to

It means if

If then, NAND=0

NAND=

If A=0 and B=0 then

Output in NAND=1

If A=0 and B=1 then

Output in NAND=1

If A=1 and B=0 then

Output in NAND=1

If A =1 and B=1 then

Then, output in NAND=0

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
