Answer:
x=9.6
Step-by-step explanation:
The dot in the middle represents the center of the circle, so therefore, the line that is represented by 16 is the radius. Since that is the radius, the side that is the hypotenuse of the small triangle is also 16, since they have the same distance.
The line represented by 25.6 with x as its bisector shows that when we divide it by 2, the other side of the triangle besides the hypotenuse is 12.8.
Now that we have the two sides of the triangle, we can find the last side (represented by x). Use pythagorean theorem:
Answer:
not one of those two...
Step-by-step explanation:
are there other options? when graphed on desmos it looks like this...
<span>First distribute the 4(5n-7);
20n-28=10n+2
Now subtract both sides by 10n and add 28 to both sides;
20n-10n=2+28
10n=30
n=3
