The answer is p v q and some other one, I haven't done logic in 2 years already, so I don't know the other one. BUT, if p is true, then p v q HAS to be true because if one of the statements, p or q, is true, then p v q is true. For or statements to be true, at least one of the statements included has to be true.

Answer:

The answer to your question is: ∠K = 138°

Step-by-step explanation:

m∠N = 42°

m∠K = ?

The sum of all the internal angles in a quadrangle equals 360°

then

∠N + ∠L + ∠M + ∠K = 360°

∠N = ∠ L and ∠M = ∠K

So, 2 ∠N + 2 ∠K = 360

Substitution

2 (42) + 2 ∠K = 360

84 + 2 ∠K = 360

2 ∠K = 360 - 84

2 ∠K = 276

∠K = 276 / 2

∠K = 138°

The temperature outside was 8 degrees below zero. The next day it went up 5 degrees, followed by a decrease of 7 degrees. What i

Tatiana [17]

Hello! Your answer would be -10 degrees.

The temperature starts out eight degrees below zero. 0 - 8 = -8. Therefore, it starts off at -8 degrees.

Then, it increases by 5 degrees. Therefore, add 5 to -8. -8 + 5 = -3. Therefore, the next day has a temperature of -3 degrees.

Finally, it decreases by 7 degrees. -3 - 7 = -10. This shows us our final result - -10 degrees.

Hope this helps!
