The downward-right acute angle is labeled left square bracket 3 left parenthesis x plus 14 right parenthesis right square bracket degrees.

Answers

t N.

In the figure shown below

Answer:

A horizontal line segment M K intersects with line segment J L at their midpoint N.

∠J N M =(5x+2)°

∠ LN M=3( x+ 14)°

So, ∠J N M + ∠ LN M =180°[ These two angles form linear pair.Angles forming linear pair are supplementary.]

⇒5 x+ 2+ 3 (x+ 14) =180 [ By Substitution]

⇒ 5 x+2 +3 x+42°= 180°

⇒ 8 x=180°-44°

⇒8 x= 136°

⇒x= 136°÷8

⇒x=17°

So, ∠J N M =5×17 +2=87°

∠ LN M= 3×(17 +14)=3×31=93

∠J N M =∠K N L [Vertically opposite angles]

∠K N L=87°

Answer:

The measure of $\angle KNL = 87\°$

Step-by-step explanation:

According to the below diagram, horizontal line segment $MK$ intersects with $JL$ at their midpoint $N$ .

So, $\angle JNM = \angle KNL$ (As they are vertical angles)

Given that, $\angle JNM = (5x+2)\°$ and $\angle MNL = [3(x+14)]\°$

As they are adjacent angles and points $J, N$ and $L$ are co-linear, so $\angle JNM +\angle MNL = 180\°$

That means.......

$(5x+2)+3(x+14)=180\n \n 5x+2+3x+42=180\n \n 8x+44=180\n \n 8x=180-44=136\n \n x=(136)/(8)=17$

Thus, $\angle KNL =\angle JNM= (5*17+2)\° = 87\°$

What is 1/4 as a whole number?

Answers

The whole number of $(1)/(4)$ is $\boxed{0.25}.$

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The number is $(1)/(4).$

Explanation:

The whole numbers is the series of numbers that starts from zero.

The natural numbers are those numbers that start from one.

The place values are only natural numbers.

The base ten systems represent the position of a place value.

The given number is $(1)/(4).$

Consider the number $(1)/(4)$ as $\text{A}$ .

$A = (1)/(4)$

Divide 1 by 4 to obtain the whole of $(1)/(4).$

$\begin{aligned}\text{A}&= (1)/(4)\n&= 0.25\n\end{aligned}$

The decimal expansion of $(1)/(4)$ is $0.25.$

The whole number of $(1)/(4)$ is $\boxed{0.25}.$

Keywords: place value, base value, decimal expansion, whole number, natural number, division, multiplication, subtraction, solve the equation, solution, linear equation, line, decimal.

Answer:

The value of the $(1)/(4)$ as a whole number is 0 .

Step-by-step explanation:

Definition of whole number

A whole number is an integer that is 0 or greater and there are no fractional or decimal numbers .

As given

$= (1)/(4)$

In the decimal form

= 0.25

(As the whole numbers are not express in the decimal form .)

= 0 (Approx)

Therefore the value of the $(1)/(4)$ as a whole number is 0 .

How do I do this equivalent ratio

Answers

The ratio given is

40:80:8

The equivalent ratio is

? : ? : 5

In the first ratio, look at the number in the same position as the 5 in the second ratio and compare it to the other 2 numbers. 80 is 10 times 8, and 40 is 5 times 8. Bring that same ratio down to the equivalent ratio...

5 x 10 = 50
5 x 5 = 25

The equivalent ratio is

25:50:5

We know that the last number on the second row is 5. What we need to know is how they got 5. We can...

The 8 on the first row is proportional to the 5 on the second row. For them to get 5 on the second row they multiplied the 8 by (5/8). I found that out by dividing the second number which was 8 by the first number which was 5.

So, 8 × (5/8) = 5. Since everything is proportional, we can multiply (5/8) to the other numbers on the first row to find out their numbers on the second row.

40 * (5/8) = 25

80 * (5/8) = 50

Those are the new numbers. If you have any questions then leave a comment. Good luck!
