To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that

we can subtract twenty from each side


now we can subtract like terms

so we can get the final answer as
(8.5*12.4)^(1/2)=10.266
In general the geometric mean is (ab)^(1/2), (abc)^(1/3), (abcd)^(1/4), etc
The nth root of the product of n elements.
Answer: H
Step-by-step explanation:
So this is called a problem you would use PEMDAS or (please-excuse-my-dear-aunt-sally)
Parenthesis
Exponents
Multiply
Divide
Addition
Subtract
In this sens, since parenthesis are present you do them first so it would be H
Answer:
C.(6, 4,2)
since every element of B is also an even number,so is an element of C
Answer: B) one
This one point is point U since it is on line segment CD. In contrast, a point like point E is not on line CD, so E is not collinear with C and D.
