Congruent Parts of a Congruent Triangle are Congruent
∠B ≅ ∠E
AB <span>≅ DE
BC </span><span>≅ EF
AB = 20
BC = 24
EF = 6
DE = x
20/24 = x/6
Solve for x, cross multiply
24(x) = 20(6)
24x = 120
24x/24 = 120/24
x = 120/24
x = 5
x = 5, or A is your answer

Answer:

Step-by-step explanation:
Hello!
To solve for x, we have to first isolate the variable.
<h3>Solve for x</h3>
The value of x is
.
Answer:
-1/2.
Change in y above change in x (don't mix that up)
The first coordinate is 3,-2 the second is 2,-4.
The change is x was -1 . (2-3)
The change in y was 2. (-4-(-2))
Answer:
Step-by-step explanation:
The vertical motion of the object is defined by using the height function h(t) such that :
h(t) = -16t² + vt + s , where t is the time instant , v is the initial velocity and s is the initial height of the object.
Now, the height of the bridge = 200 feet
So it would be the initial height ⇒ s = 200
Initially the speed is 0 because the body is in rest at time instant 0 sec.
Hence, the resultant equation is : h(t) = -16t² + 200
And the graph is attached below :
Answer: Degree = 3
Explanation:
The degree of any single variable monomial is simply the exponent itself.
For stuff like
, you'll need to add the exponents to determine the degree.
