Answer:
3 and 6
4 and 5
Step-by-step explanation:
Alternate interior angles are on the opposite sides of the transversal, t, and between the parallel lines, r and s
3 and 6 are alternate interior angles
4 and 5 are alternate interior angles
Answer:
4d (the variable is usually x, though).
Step-by-step explanation:
Because 4 x the amount of fish in each tank = total amount of fish
Given:
m∠D = 5x - 10
m(ar EC) = 60°
m(ar RB) = 13x + 7
To find:
The value of x.
Solution:
<em>If two secants intersect outside a circle, then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>



Multiply by 2 on both sides.


Add 53 on both sides, we get

Subtract 10x on both sides, we get

Divide by 3 on both sides, we get

The value of x is 11.
The perimeter is 28 bc 5+5 is 10 and 9+9 is 18 so if you add 10 and 18 you get 28. Hope it helps:)
