Hi! Do you know the similar triangle rules?
I will prove one for you and you can try the rest
ΔCBD ~ ΔABC proof:
st | r
1) ΔABC is right Δ | Given
2) CD is alt to hyp | Given
3) m∠C = 90° | def right Δ
4) m∠CDB = 90° | def alt
5) m∠B = m∠B | reflexive property (more triangles share ∠B)
6) ΔCBD ~ ΔABC | AA (since two angles are equal, the two triangles are similar)
We do not need to prove all three angles as similar since if two corresponding angles of two triangles are congruent, the third has to be equal (since the total sum of angles is 180° in a triangle)
You can translate the statement reasoning into a paragraph
I hope this helps! If not, let me know and I will try and explain further :)

Step-by-step explanation:
A pentagon's angle all add up to 540
[tex]460+x=540[/tex]
[tex]x=80[/tex]
Answer:A 80
Step-by-step explanation:
So a square is all 90° angles so take 90 from 140 and get 50 and 50+50=100 and a triangles thing adds up to 180 so 180-100=80 (I’m not good at explaining sorry)

Answer: x= 30

These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x
Patty rolls a six-sided number die 120 times. How many times should she expect to roll a
prime number?
Answers
Answer is 60 times.
Explanation:
Prime numbers in a die are 2, 3 and 5 (i.e. 3 numbers)
Total outcomes can be 1, 2, 3, 4, 5 and 6 (i.e. 6 numbers)
Probability
= Number of preferred outcomes/ Total number of outcomes
= 3/6
= 1/2
= 0.5
Probability of getting a prime number while throwing the dice 120 times
= 0.5 × 120
= 60 times

since the angle given is a complementary angle, we know that the sum of it must equal 180°
let the unknown angle below j be x so,
[tex]25+43+x=180\\x=180-25-43\\x=112[/tex]
now since the angle on the left of j is equal to x we can say

Solve the following expression when
x=4 and y=10
6x - 3x + 5 - y
Answers
Answer:
7
Step-by-step explanation:
We can simplify this because 6x - 3x is equal to 3x, so we get that the expression is 3x - y + 5. Next, we can plug in our values. 3 * 4 - 10 + 5 is equal to 12 - 10 + 5, which is 2 + 5, which is 7.
The value of the expression 6x - 3x + 5 - y at x = 4 and y = 10 is 7.
What is substitution?Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.
Given, An expression 6x - 3x + 5 - y.
Now, The value of the expression at x = 4 and y = 10 can be obtained by replacing the numerical values of x and y.
Therefore, 6x - 3x + 5 - y at x = 4 and y = 10 is,
6(4) - 3(4) + 5 - 10.
= 24 - 12 + 5 - 10.
= 12 - 5.
= 7.

Answers
9514 1404 393
Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

A truck is carrying 8 cars weighting an average of 4500 pounds each. What is the total weight in tons of the cars on the truck?
Answers
Answer:
the total weights in tons is 18
Step-by-step explanation:
The computation of the total weights in tons is shown below:
The weight of 8 cars would be
= 4,500 pounds × 8 cars
= 36,000 pounds
Now as we know that 1 ton = 2,000 pounds
So for 8 trucks it would be
= 36,000 pounds ÷ 2,000 pounds
= 18 tons
Hence, the total weights in tons is 18
