Find the value of x. give reasons to justify your answer NEED HELP ASAP!!!!

Firlakuza [10]

Answer:

$x = 34^\circ$

Step-by-step explanation:

Note that ∠TSU and ∠PSR are vertical angles. Hence:

$m\angle TSU = m\angle PSR$

∠PSR is the sum of ∠PSQ and ∠QSR. Hence:

$\displaystyle m\angle TSU = m\angle PSQ + m\angle QSR$

We know that ∠TSU measures 4<em>x</em> and ∠QSR measures 3<em>x</em>. Thus:

$(4x) = m\angle PSQ + (3x)$

Solve for ∠PSQ:

$m\angle PSQ = x$

Next, ∠PQS and ∠RQS form a linear pair. Thus:

$m\angle PQS + m\angle RQS = 180^\circ$

∠RQS measures 68°. Thus:

$m\angle PQS +(68^\circ) = 180^\circ$

Solve for ∠PQS:

$m\angle PQS = 112^\circ$

The interior angles of a triangle must total 180°. So, for ΔPQS:

$\displaystyle m\angle SPQ + m\angle PQS + m\angle PSQ = 180^\circ$

Substitute in the known values:

$(x) + (112^\circ) + (x) = 180^\circ$

Simplify:

$2x = 68^\circ$

And divide. Hence:

$x = 34^\circ$

Is the equation true, false, or open? Explain. 20-1=1+17

Bad White [126]

Answer:

false

Step-by-step explanation:

20 - 1 = 1 + 17

Simplify each side.

19 = 18

Since 19 = 18 is a false statement, the equation is false.

Find the y? 3x + 6y = 12

kari74 [83]

Could you give Brainliest please???

Answer:

y = 2 - 1/2x

Step-by-step explanation:

So we are given the equation 3x + 6y = 12 and are ask to find y.

To find y you must isolate it first.

3x + 6y = 12

(Subtract 3x to isolate the y term)

6y = 12 - 3x

(Divide both sides by 6 to isolate the variable)

y = 2 - 3/6x

(Simplify)

y = 2 - 1/2x

And that is your answer since there is a second variable.

Solve for angle C please

zubka84 [21]

Answer:

13.3 cm

Step-by-step explanation:

We can use the Pythagoream Theorem to identify any missing angles!

$a^{2} +b^2=c^2$

In this case, will leave c for a^2!

$a^2+20^2=24^2$

$a^2+400=576$

$576-400=a^2$

$a^2=176$

$\sqrt{176} = 13.3$
