Answer:
AC congruent to EC
Step-by-step explanation:
This problem is asking specifically to prove triangles congruent using HL.
HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.
Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.
You need AC congruent to EC.
Your answer would be ABO and BCO
The formula for the volume of a cone is

Answer:
x = 1. y = -3
Step-by-step explanation:
Add the two equations together and notice that all terms containing y will disappear, leaving with
10x = 10 or x = 1
Using this value of x into either one of the equations, you'll get
4(1) + 3y = -5 ---> 3y = -9 or y = -3
Answer:
-2x=3y (we have 9 more) = 9
-4 = 5 x=-4 =9 as -4+5=1
-2x=3y = 1
= +-4 + 4 = 8 + 1 = 9
y=5
As -2x=3y = 1
= +-4 + 4 = 8 +1 = 9
+ 5 +5 +5 = 15
