Answers

Answer 1

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

Answer 2

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°

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?

Answers

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].

Answers

X=112
Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!

Answer:

x = 118°y = 84°

Step-by-step explanation:

We observe that:

x = y + 22 as exterior angle of the triangle is the sum of non-adjacent interior angles.

Also:

x = 118 as corresponding angles formed by two parallel lines and a common transversal.

Find the value of y:

y = x - 22y = 118 - 22y = 84


[tex] - \frac{x}{5 } = 25[/tex]
what is the answer ​

Answers

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

Step-by-step explanation:

Since       (20)        =        (-3)                     [we can cross multiply]

            (x²- 25)                (5-x)

Answers

no because

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.
