Answer:
Step-by-step explanation: Triangle ABC is congruent to triangle DEF. Angle B is a right angle, and m∠C = 57°. What is m∠D? can someone help plsss
If Triangle ABC is congruent to triangle DEF then measure of angle D is 48 degrees.
Given, Triangle ABC is congruent to triangle DEF.
Angle sum property of triangle: Sum of all the interior angles of the triangle is 180 degrees.
Congruent triangles: When two triangles are congruent they are similar in shape and coincide when superimposed.
Now in triangle ABC,
∠B = 90°
∠C = 42°
Apply angle sum property,
∠A + ∠B + ∠C = 180 degrees
∠A + 90° + 42° = 180°
∠A = 48°
When Triangle ABC is congruent to triangle DEF,
∠A = ∠D
∠B = ∠E
∠C = ∠F
Thus measure of angle D is equal to measure of angle A.
∴∠A = ∠D = 48°

Find the equation for the vertical line that goes through point V (−5, 17).
Answer:
x = 17
Step-by-step explanation:
y = 17 because in a vertical line the x value does not change
Answer:
x = -5
Step-by-step explanation:
The Y value will never change. Its a straight line going from up to down and it runs over the point (-5, 17) . Y can be an infinite number and the equation won't change.

B. AXYZ is similar to and congruent to AX'Y'Z'
C. AX'Y'Z' is a 180° clockwise rotation of AXYZ
D. AXYZ is similar to but not congruent to AX'Y'Z'
ANSWER:
The answer is A
When Triangle XYZ is reflected over the x-axis, D. ∆XYZ is similar to but not congruent to ∆X'Y'Z'.
What is a triangle?A triangle simply means a shape that has three sides as well as an angle that's equal to 180°.
In this case, when triangle XYZ is translated by the rule (x + 3, y - 2) and then reflected over the x-axis, it's not congruent because they don't have same size and shape.

sorry if i am wrong.
Step-by-step explanation:
281=48-u
281-48=48-u-48 ( substracting 48 on both sides )
233=-u

[tex] - \frac{x}{5 } = 25[/tex]
what is the answer
Answer:
x = -125
Step-by-step explanation:
Step 1: Multiply both sides by -5.
[tex]-\frac{x}{5}* (-5) = 25 * (-5)[/tex] [tex]x = -125[/tex]Step 2: Check if solution is correct.
[tex]-\frac{(-125)}{5} = 25[/tex] [tex]-(-25)=25[/tex] [tex]25=25[/tex]Therefore, x = -125.
Answer:
x = - 125
Step-by-step explanation:
- [tex]\frac{x}{5}[/tex] = 25 ( multiply both sides by 5 to clear the fraction )
- x = 125 ( multiply both sides by - 1 )
x = 125
do you need to regroup to subtract 881 from 4,986 how do u know?
no because
4986
881
4 1 0 5
there is no regrouping because every top number is equal to or larger than the bottom number
There is no need to regroup to subtract 881 from 4,986, the answer would be 4105.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The two numbers are:
881 and 4986
As we know,
The term PEDMAS describes the sequence in which arithmetic operations must be carried out in an equation.
According to this rule, operations should be carried out in the following order: parentheses, exponents, multiplication or division, then addition or subtraction.
After applying the concept of arithmetic operation:
= 4986 - 881
= 4105
Thus, there is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

An airplane begins its decent toward the airport, modeled by the function
A(t)=29500−500t , where t is in minutes and A(t) is in feet.
What is the domain of the function within the context?
Using function concepts, it is found that the domain in this context is [tex]0 \leq t \leq 59[/tex].
The domain of a function is the set that contains all possible input values.In this problem, the height of the airplane after t seconds is modeled by:
[tex]A(t) = 29500 - 500t[/tex]
This function is only valid for non-negative values of t, that is, [tex]t \geq 0[/tex], and for non-negative altitudes, that is:
[tex]A(t) \geq 0[/tex]
Thus:
[tex]29500 - 500t \geq 0[/tex]
[tex]-500t \geq -29500[/tex]
[tex]500t \leq 29500[/tex]
[tex]5t \leq 295[/tex]
[tex]t \leq \frac{295}{5}[/tex]
[tex]t \leq 59[/tex]
Thus, the domain for the function in this context is: [tex]0 \leq t \leq 59[/tex].

(20)/(x^2-25)=(-3)/(5-x)
Thank You
Since (20) = (-3) [we can cross multiply]
(x²- 25) (5-x)
⇒ (20)(5 - x) = (-3)(x² - 25) [expand the brackets]
⇒ 100 - 20x = -3x² + 75 [make the equation equal to zero]
⇒ 3x² - 20x + 25 = 0 [expand the middle term using
appropriate factors of the product
of the terms a and c (3 × 25)]
⇒ 3x² - 15x - 5x + 25 = 0 [factorize the terms]
⇒ (3x - 5 ) (x - 5) = 0 [using the knowledge that for the
produc to be 0, one of terms
must be zero]
⇒ (3x - 5 ) = 0 OR (x - 5) = 0 [solve for x in each case]
⇒ x = ⁵/₃ OR x = 5
