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.
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
I think the question 23 is e.
Step-by-step explanation:
As we have to use the number 0-6 once to make 2 equivalent ratios.
so lets solve the problem.
Determining first equivalent ratio
as
and

Therefore, first equivalent ratio

Determining second equivalent ratio

as

and

Therefore, second equivalent ratio
