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

A soccer field has a perimeter of 326 metres. Its area is 6370 square metres. What are the dimensions of the field?

Burka [1]

Answer:

Step-by-step explanation:

chiều dài:x,x>0

chiều rộ:y

$\left \{ {({x+y)*2=326} \atop {xy=6370}} \right.$

$\left \{ {{x+y=163} \atop {xy=6370}} \right.$

$\left \{ {{y=163-x} \atop {xy=6370}} \right.$

$\left \{ {{y=163-x} \atop {x*(163-x)=6370}} \right.$

$\left \{ {{y=163-x} \atop {163x-x^{2} =6370}} \right. \\$

$\left \{ {{y=163-x} \atop {x_{1} =98; x_{2} =65}} \right.$

$\left \{ {{y=65} \atop {x=98}} \right.$
