Solve by taking the square root of both sides.
horrorfan [7]

Answer:

a

Step-by-step explanation:

Given

3(x + 3)² - 81 = 0 ( add 81 to both sides )

3(x + 3)² = 81 ( divide both sides by 3 )

(x + 3)² = 27 ( take the square root of both sides )

x + 3 = ± \sqrt{27} = ± 3\sqrt{3} ( subtract 3 from both sides )

x = - 3 ± 3\sqrt{3}

x = - 3 - 3\sqrt{3} or x = - 3 + 3\sqrt{3} → a

FAST!! Evaluate tan60/cos45<br> √6<br> √3/2<br> √2/3<br> 1√6
evablogger [386]

Answer:

\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}

Step-by-step explanation:

We want to evaluate

\frac{\tan 60\degree}{\cos45 \degree}

We use special angles or the unit circle to obtain;

\frac{\tan 60\degree}{\cos45 \degree}=\frac{\sqrt{3}}{\frac{\sqrt{2}}{2}}

This implies that;

\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\div \frac{\sqrt{2}}{2}

\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\times \sqrt{2}

\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}

Pls ans both the questions im very confused
lions [1.4K]

Answer:

Step-by-step explanation:

In Δ PQS and ΔPQT

∠QPS = ∠RPT       {Common angle}

∠PSQ = ∠PTR = 90°         {QS & RT are altitude}

QS = RT                            {given}

ΔPQS ≅ ΔPRT               {A A S congruent}

PQ = PS                         {CPCT}

So, PQR is an isosceles triangle.

9)

a) Flas card (I) and (iii) are congruent.

b)  A S A congruent

c) BC ≅ RP
