They affect the signs of p and q in different ways.
Firstly, if c is negative, it means that p and q have opposite signs.
If c is positive, then it means that p and q have the same signs. However, to determine whether they are both positive or both negative, we then have to look to b. If b is negative, both p and q would be negative. If b is positive, then both p and q are positive.
Answer:
x = 18
Step-by-step explanation:
To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:
x + 72 = 5x
Since this gives us an equation, we can just solve for x:
x + 72 = 5x
72 = 4x
x = 18
Step-by-step explanation:
From the Pythagorean theorem we have:
<em>subtract b² from both sides</em>

Answer:
23.7555090109
Step-by-step explanation:
sin= opposite/hypotenuse
sin(53) = BC/60cm
BC= sin(53)*60 = 23.7555090109
