Answer:
A
Step-by-step explanation:
They are basically wanting the value of x.
These are 2 secant lines drawn. Secant Line is a line that intersects the circle at 2 points.
To solve this, we have to use secant-secant theorem.
Secant-Secant Power Theorem tells us that if 2 secant lines are drawn from external point (here, E) to a circle, then, product of measure of one secant's external part and total secant is equal to other secants external part and whole secant.
In algebra, that is:

Let's multiply and find the value of x:

Hence, the correct answer choice is A
Answer:
The equation for the given maths problem is $ 34 + $ 8x = $ 90
Step-by-step explanation:
According to question :
The Total amount spent on cloths = $ 90
The cost of a pair of jeans = $ 34
The cost of each t-shirt pair = $ 8
The amount spent on t-shirt = $ 90 - $ 34 = $ 56
Let the number of t-shirt pair = x
So, $ 34 + $ 8x = $ 90
Or, $ 8x = $ 90 - $ 34
∴ x = 
Hence The equation for the given maths problem is $ 34 + $ 8x = $ 90 Answer
Answer:
17 units
Step-by-step explanation:
Because the triangle is isosceles, 2 of its sides are congruent; namely, the two sides that are opposite of the 2 congruent angles are contruent.
Because of the reason stated above, we can see that AC is congruent to BC, meaning that:
x+9=2x-8
-x -x
9=x-8
+8 +8
17 = x
Notice that BC is equal to x, so 17 is our final answer.
