Answer:

$x=7,\\y=6$

Step-by-step explanation:

The segment $UV$ consists of $UZ$ and $VZ$ . Therefore, we can write the following equation:

$3y-5+2y+2=27,\\5y-3=27,\\5y=30,\\y=\fbox{$6$}$ .

Since $UV$ bisects $TW$ , $TZ\cong WZ$ .

Therefore,

$3x+3=3y+6,\\3x+3=3(6)+6,\\3x+3=18+6,\\3x+3=24,\\3x=21,\\x=\fbox{$7$}$

Solve the system of linear equations. separate the x- and y- values with a coma.

kobusy [5.1K]

Solve the following system:
{7 x - 3 y = 37 | (equation 1)
{14 x + 11 y = 23 | (equation 2)
Swap equation 1 with equation 2:
{14 x + 11 y = 23 | (equation 1)
{7 x - 3 y = 37 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{14 x + 11 y = 23 | (equation 1)
{0 x - (17 y)/2 = 51/2 | (equation 2)

Multiply equation 2 by 2/17:
{14 x + 11 y = 23 | (equation 1)
{0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:
{14 x + 11 y = 23 | (equation 1)
{0 x+y = -3 | (equation 2)
Subtract 11 × (equation 2) from equation 1:
{14 x+0 y = 56 | (equation 1)
{0 x+y = -3 | (equation 2)

Divide equation 1 by 14:
{x+0 y = 4 | (equation 1)
{0 x+y = -3 | (equation 2)
Collect results:
Answer: {x = 4
{y = -3

What is the measure of the third angle?

SCORPION-xisa [38]

The total amount of degrees in a triangle is 180. All three angles should add up to 180˚

We know that 40+60 = 100

The next step is to do 180-100 to get the other angle.
180-100 = 80

So the measure of the third angle is 80˚

Hope this helps!

(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)

Find all solutions of the equation sin^2 x=2sinx+3

Mashutka [201]

$\sin^2x=2\sin x+3$
$\sin^2x-2\sin x-3=0$
$(\sin x-3)(\sin x+1)=0$

which means either $\sin x=3$ or $\sin x=-1$ . The equation has no solution, since $\sin x$ is always bounded between -1 and 1. The second has one solution at $x=-\dfrac\pi2$ , and any number of complete revolutions will also satisfy this equation, so in general the solution would be $-\dfrac\pi2+2k\pi$ where $k$ is any integer.

So you could choose $A=-\dfrac\pi2$ and $B=2$ .
