Step-by-step explanation:
Look at the image I attached for reference as I explain. (I only labeled the angles that are relevant to the problem)
These triangles are congruent, as shown by the first equation.
When triangles are congruent, it means that the sides and angles are the same.
We can see that angles ∠ABC and ∠DEC are corresponding, which means that they have the same value.
We don't know ∠DEC, but we have two angles in that triangle that we do know. Since the angles in a triangle add up to 180, we have this equation:
180-65-55=∠DEC
60 = ∠DEC
So now we know that ∠DEC is 60 degrees.
Since ∠ABC and ∠DEC are equal:
2x=60.
Divide both sides by 2, and we get x =30.

I'm not 100% sure, but I think the answer is 10 units squared.
Step-by-step explanation:
Find the area of each triangle, by multiplying each side, and dividing the answer in half. Add both of the triangles together, ending up as 6. Now we just find the area of the square. 2x2=4, add that to both of the triangles, and we're done. (2x2) ÷ 2 = 2 | (2x4) ÷ 2 = 4 | 2x2 = 4 | 4+4+2=10
Answer:
area=10 units^2
Step-by-step explanation:
[tex]a=\frac{(2+2+4)+(2)}{2} *2\\ =\frac{8+2}{2} *2\\ =\frac{10}{2} *2\\ =5*2\\ =10[/tex]
a=10 units^2

You have two decks of cards and you select a card from each deck. What is the probability to selecting a jack both times?
Answers
Answer:
The probability is 1/13 (1 to 13).
Step-by-step explanation:
In a card deck, there are 52 cards with 4 Jacks. If you simplified this probability, the answer would be 1 to 13.
4/52 = 1/13
In two card decks, there are 104 cards with 8 jacks. If you simplified this probability, the answer would also be 1 to 13.
8/104 = 1/13

find the excerpted value
Answers
Answer:
The expected value is $4.35
Step-by-step explanation:
Here, we want to find the expected value
To
do that, we simply will multiply each of the payouts by the individual probabilities, then add the results
Mathematically, we have this as;
0.35(1) + 0.2(2) + 0.1(5) + 8(0.2) + 10(0.15)
= 0.35 + 0.4 + 0.15 + 1.6 + 1.5 = $4.35

solve each system by substitution
1/2x+1/3y=6
x-y==2
Answers
Step-by-step explanation:
First, let's rewrite the equations.
1/2x + 1/3y =6
x - y = 2
The easiest system to use for substitution is the second one. Let's solve for X.
x - y = 2
add y to both sides!
x = 2 + y
Now that we know x = 2 + y we can use it to substitute in the first equation.
1/2(2 + y) +1/3y = 6
1 + 1/2y +1/3y = 6
5/6y = 5
y = 36/5
Solve for X, show work PLS =)
