Answer:
X_2
Step-by-step explanation:
X_2/5+2X+1/2= 12x_1/10
Answer:
P(A∩B)=P(A)*P(B)
Step-by-step explanation:
In this problem, we need to plug in the given x values for

and find a and b.
When we plug in 1, we get:

Simplify:



We got our first statement about the values of the variables. If we find one more we can find those 2 variables.
We have another given root: 4.
Plug it in:




Now we have our second one. We can combine them:

I use elimination method which is easier here.
Multiply the top equation by -1:

Add them up:

Simplify:

Now we have a, we can plug in one of those equations to find b:



So, the answers are

and

.
There are three more angles with the same measure. A pair of corresponding angles and a pair of vertical angles.
