Answer: 76 degrees

In order to solve for the ? Angle you can use inverse tangent with our given sides
The original equation for inverse tangent is tan^(angle)=opposite/hypotenuse, so plug the values in, and isolate the angle by dividing tangent. Then solve on a calculator and let x=?; tan^-1(40/10) which is equal to 75.96375653 which is approximately 76 degrees

Find measure.<br> m ∠ 5

jeka57 [31]

Measure of angle 5 i.e. m∠5 = 50°

<h3>What is measurement of an angle ?</h3>

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

<h3>How to find angle measurement ?</h3>

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

1/4b^2+ 4bc + 16c?<br> Answer?

Charra [1.4K]

Answer:

1/4b^2+ 4bc + 16c?=4

Step-by-step explanation:

STEP

Simplify —

Equation at the end of step

((— • b2) + 4bc) + 16c

STEP

Equation at the end of step 2

(—— + 4bc) + 16c

STEP

Rewriting the whole as an Equivalent Fraction

3.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 4 as the denominator :

4bc 4bc • 4

4bc = ——— = ———————

1 4

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

b2 + 4bc • 4 b2 + 16bc

———————————— = —————————

4 4

Equation at the end of step

(b2 + 16bc)

——————————— + 16c

STEP

Rewriting the whole as an Equivalent Fraction

4.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 4 as the denominator :

16c 16c • 4

16c = ——— = ———————

1 4

STEP

Pulling out like terms

5.1 Pull out like factors :

b2 + 16bc = b • (b + 16c)

Adding fractions that have a common denominator :

5.2 Adding up the two equivalent fractions

b • (b+16c) + 16c • 4 b2 + 16bc + 64c

————————————————————— = ———————————————

valentina_108 [34]

Step-by-step explanation:

$\frac{5}{2} = \frac{x - 4}{3}$

$3 \times \frac{5}{2} = \frac{x - 4}{3}$

$\frac{3}{1} \times \frac{5}{2} = \frac{x - 4}{3}$

cross multiplication

$\frac{6 \times 5}{2} = \frac{x - 4}{3}$

$15 = \frac{x - 4}{3}$

$15 \times 3 = x - 4$

$45 + 4 = x$

$49 = x$

An object in a simulation accelerates

notsponge [240]

Observe the graph below. This graph represents the scenario.

The question is ill formated, the complete question is

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

Observe the graph below. This graph represents the scenario.
