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
Angle mpd is complementary to angle dpb meaning they add up to 90 degrees. angle apc is equal to angle dpb because they are vertical angles created by 2 intersecting lines
Answer:
120
Step-by-step explanation:
A proportion can be called as an equation to check two ratios are equal to each other or not.
Whenever the terms of a proportion are cross multiplied, the cross products will always be equal.
So to check this we can find the cross products to check if two ratios are equal and if they are equal,they are in proportion. To find the cross products of a proportion, we multiply the extremes, and the means.
Answer:
Answer - -5
Step-by-step explanation:

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below
that means, the squared variable is the "x", thus the form is

now, we know the vertex is at 0,1, and two x-intercepts of

thus

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
