Answer: x=5, angle 1 = 140 degrees, angle 2 = 40 degrees, angle 3 = 65 degrees
Step-by-step explanation:
1)
19x-18=(7x+1)+(10x-9)
19x-18=17x-8
2x=10
x=5
2)
angle 1 = 60+80
angle 2= 180-(60+80) or 180-angle 1
angle 3 = 180 - (180-105) - angle 2 = 105 - angle 2

Answer: set of rational numbers, set of real numbers</h3>
Explanation:
The number -1/2 is rational as it is a fraction or ratio of two integers (-1 and 2). We can never have 0 in the denominator. Since it is rational, it means the number is not irrational. Recall that "irrational" means "not rational", so it is the opposite of rational.
-1/2 = -0.5 is not a whole number as it has a fractional or decimal portion. This means -1/2 is not an integer either, nor is it a natural number. The negative portion is another reason to exclude -1/2 from the list of whole numbers and natural numbers.
But we can say that -1/2 = -0.5 is a real number. Any number you encountered so far is a real number until you get to the complex numbers.
