Use the pythagorean theorem: a^2 + b^2 = c^2
24^2 + 7^2 = x^2
576 + 49 = x^2
x^2 = 625
√x^2 = √625
x = 25
Answer:
m arc NP = 151°
Step-by-step explanation:
m arc MN = x
m arc NP = y
5x + 6 = y
x + y = 180, I will solve with substitution
x + (5x + 6) = 180
6x + 6 = 180
6x = 174
x = 29
y = 151
Answer:

Step-by-step explanation:
First using the Pythagorean theorem, we know the hypotenuse
is 39 and one of the legs
is 36. So we would have:

So we have our answer as 
Hope this helps.
Let x be the number.
Then;
6x-18=-42 (solve for x now)
6x=-42+18
6x=-24
x=-4
Therefore, this number would be -4.
Hope I helped :)
