Question

If p∨q is true, then what must be true about the truth values of p and q?

both are true
both are false
at least one is true

Answer 1

at least one is true

Answer 2

thank you! i have one more

Answer 3

Two angles are complementary. One of the angles is twice the other.

The larger angle has a measure of

120°
60°
45°

Answer 4

I am not sure how to do this problem. I know that complimentary means that the angles add up to 90 degrees.

Answer 5

let one angle is x and the other 2x
x+2x = 90
solve for x

Answer 6

Thirty degrees?

Answer 7

Oh it is 45!

Answer 8

yes, x = 30
obviously as the the larger is 2 * 30 = 60

Answer 9

So it isnt 45 degrees?

Answer 10

no, it is 60 (twice of x)

Answer 11

with x is the first angle

Answer 12

ok, the reason that i thought that is because :
x+2x = 90
I divided both 2x and 90 by two and was left over with x=45.
But i see that you are right:)

Answer 13

Thank You!

Answer 14

x+2x=3x

so, we have 3x = 90
divide by 3 to both sides
x = 90/3 = 30

you're welcome

Answer 15

Thank you for clarifying how to do this problem:)
