Answer:
the vertex angle = 80°
Step-by-step explanation:
V: vertex angle B: base angle
V / B = 8 / 5
5V = 8B
V + 2B = 180
4V + 8B = 720
4V + 5V = 720
9V = 720
V = 80°
check: B = (180 - 80) / 2 = 50°
V / B = 80 / 50 = 8 /5 (8 : 5)
Answer:

Answer:
The quotient of any nonzero integers, a and b, is always a rational number.
Step-by-step explanation:
We know that a rational number is any number that can be written in the
form of , where q is not equal to zero.
- p/q is basically the quotient of integers (non-zero).
p and q integers mean they are rational number. As the quotient is generated by the division of these two numbers, and q is not equal to zero.
- As q can be equal to 1, so every integer is a rational number.
Therefore, the quotient of any nonzero integers, a and b, is always a rational number.

Answer:
3 items are in B that are not in C
Step-by-step explanation:
a: only in a, not count those in b or c
b: only in b, not count those in a or c
c: only in c, not count those in a or b
A = a + b + c = 20
c = 7
a + b = 20 - 7 = 13
10 not in b, of course not in c ∴ a = 10
b = 13 -10 = 3
