Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
Answer:
4/(3(x-2))
Step-by-step explanation:
3x^2-21x+30=3(x^2-7x+10)=3(x-5)(x-2)
3x-15=3(x-5)
----------------------------
So the common denominator must be 3(x-5)(x-2)
2(x-2)=2x-4
Add the numerators,
(2x-16)+(2x-4)=4x-16-4=4x-20
-----------------
(4x-20)/[3(x-5)(x-2)]
simplify 4x-20 into 4(x-5)
cancel out the (x-5)'s for both the denominator and the numerator
4/[3(x-2)]

1 is G, 2 is E, 3 is D, 4 is C, and 5 is A. But I might be misunderstanding this too.
Answer:
The value of P(A or B or C) is 0.382.
Step-by-step explanation:
Given,
P(A) = 0.169,
P(B) = 0.041,
P(C) = 0.172
Since, if events A, B and C are mutually events ( in which no element is common ),
Then, P(A∪B∪C) = P(A) + P(B) + P(C)
Or P(A or B or C) = P(A) + P(B) + P(C),
By substituting the values,
P(A or B or C) = 0.169 + 0.041 + 0.172 = 0.382
