Answer:

R1: Given

R2: Subtraction Property of Equality

R3: Distribute Property

R4: Addition Property of Equality

R5: Division Property of Equality

Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4

Prove: m∠3 + m∠1 + m∠2 = 180°

Given: ∠1 + ∠2 = ∠ 4

∠4 + ∠3 must be 180° because they are supplementary

If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.

Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.

Answer is attached in images

Step-by-step explanation:

Given:

x+z=1 and

$z=4-x^{2} -y^{2}$

Now,

$1-x=4-x^{2} 2-y^{2} 2\\x^{2} -x+y^{2} \\x^{2} -x+1/4+y^{2} =3\\(x-1/2)^{2} +y^{2} =3+1/4\\(x-1/2)^{2} +y^{2} =(\sqrt(13)/2)^{2}$

Which is circle with center (1/2,0) radius

$\sqrt{13/2}$ take, $x=1/2+\sqrt{3} /2 cos\alpha \\y=\sqrt{13}/2 sin\alpha 0\leq \alpha \leq 2\pi$

Now,

Figure out this number pattern:<br>1,5,14,30,55

Amanda [17]

5 - 1 = 4 = 2^2

14 - 5 = 9 = 3^2

30 - 14 = 16 = 4^2

55 - 30 = 25 = 5^2

Start with 1, then add 2^2, 3^3, 4^2, 5^2, 6^2, etc.
