Formula for rectangle: A=lw || Formula for triangle: A=bh/2 || Formula for circle: πr²
Now we solve:A
A= (3ft)(4ft)
= 12 ft
A= (6ft)(4ft) /2
= 24 / 2
= 12 ft
A= (3.14)(8)²
= (3.14)(64)
= 200.96 ft
12 + 12 + 200.96 = 224.96 ft ²

The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angle

Oduvanchick [21]

Answer:

The two angles are 25.5 and 114.5

Step-by-step explanation:

x = measure of one angle

5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}

x + 5x - 13 = 140 {sum of the two angles is 140}

6x - 13 = 140 {combined like terms}

6x = 153 {added 13 to each side}

x = 25.5 {divided each side by 6}

5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}

Can someone please help me with this (make sure it’s right)

Mekhanik [1.2K]

Step-by-step explanation:

$\tan \angle A = \frac{3}{6} \\ \\ \therefore \: \tan \angle A = 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} 0.5 \\ \\ \therefore \: \angle A = { \tan}^{ - 1} tan(26.565051177 \degree) \\ \\ \therefore \: \angle A = 26.57 \degree$

PLS HELP! GIVING BRAINLIST!

svlad2 [7]

Answer:

We conclude that (4, 2) is NOT a solution to the system of equations.

Step-by-step explanation:

Given the system of equations

$y = x - 2$

$y = 3x + 4$

Important Tip:

In order to determine whether (4, 2) is a solution to the system of equations or not, we need to solve the system of equations.

Let us solve the system of equations using the elimination method.

$\begin{bmatrix}y=x-2\\ y=3x+4\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}y-x=-2\\ y-3x=4\end{bmatrix}$

Subtract the equations

$y-3x=4$

$-$

$\underline{y-x=-2}$

$-2x=6$

Now, solve -2x = 6 for x

$-2x=6$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{6}{-2}$

Simplify

$x=-3$

For y - x = -2 plug in x = -3

$y-\left(-3\right)=-2$

$y+3=-2$

Subtract 3 from both sides

$y+3-3=-2-3$

Simplify

$y=-5$

The solution to the system of equations is:

(x, y) = (-3, -5)

Checking the graph

From the graph, it is also clear that (4, 2) is NOT a solution to the system of equations because (-3, -5) is the only solution as we have found earlier.

Therefore, we conclude that (4, 2) is NOT a solution to the system of equations.
