Which of the following is the measure of angle RCP?

enyata [817]

Answer:

From the information provided we have:

PD ≅ RD (= 11)

∠CPD ≅ ∠CRD (= 90°)

They both have CD as the hypotenuse.

=> ΔCPD ≅ ΔCRD

=> ∠PCD ≅ ∠RCD

Now we know that:

∠RCP = ∠PCD + ∠RCD

∠RCP = 2 · ∠RCD

∠RCP = 2 · 33° = 66°

So the answer is B

Answer:

$\large\boxed{\dfrac{5}{10}}$

Step-by-step explanation:

$\sqrt[3]{\dfrac{125}{1000}}\qquad\text{use}\ \sqrt[n]{\dfrac{a}{b}}=\dfrac{\sqrt[n]{a}}{\sqrt[n]{b}}\\\\=\dfrac{\sqrt[3]{125}}{\sqrt[3]{1000}}=\dfrac{5}{10}\\\\\\\sqrt[3]{125}=5\ because\ 5^3=125\\\\\sqrt[3]{1000}=10\ because\ 10^3=1000$

HURRY UP!!!<br>-100 = -t/5 - 4<br><br>please find t! (Explain aswell)

FrozenT [24]

Answer:

$t=480$

Step-by-step explanation:

Given

$-100 = -\frac{t}{5} - 4$

Required

Solve for t

$-100 = -\frac{t}{5} - 4$

Add 4 to both sides

$4-100 = -\frac{t}{5} - 4+4$

$4-100 = -\frac{t}{5}$

$-96 = -\frac{t}{5}$

Multiply both sides by -5

$-5*-96 = -\frac{t}{5} *-5$

$-5*-96 = t$

$480 = t$

$t=480$
