8 0

Answer:

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 9² = 15²

x² + 81 = 225 ( subtract 81 from both sides )

x² = 144 ( take the square root of both sides )

x = $\sqrt{144}$ = 12 → B

Given: PRbisects ZQPS, PQ = 12units, and PS= 12units

Ganezh [65]

Answer:

Use SAS to show that triangles PRQ and PRS are congruent.

Step-by-step explanation:

Since PR bisects angle QPS, angles QPR and SPR are congruent. By reflexive property of congruence, PR is congruent to itself. Since PQ is congruent to PS, we can use SAS to show that the two triangles are congruent. By CPCTC, QR is congruent to SR.

3-x=5x+21

vlada-n [284]

Answer:

<h3> $\boxed{ \sf{ \bold{- 3}}}$ </h3>

Step-by-step explanation:

$\sf{3 - x = 5x + 21}$

Move 5x to left hand side and change it's sign

⇒ $\sf{ - x - 5x + 3 = 21}$

Move 3 to right hand side and change it's sign

⇒ $\sf{ - x - 5x = 21 - 3}$

Collect like terms

⇒ $\sf{ - 6x = 21 - 3}$

Subtract 3 from 21

⇒ $\sf{ - 6x = 18}$

Divide both sides of the equation by -6

⇒ $\sf{ \frac{ - 6x}{ - 6} = \frac{18}{-6}}$

Calculate

⇒ $\sf{x = -3}$

Hope I helped!

Best regards!!
