Answer: 82.5 - x = R sorry if I am wrong

Step-by-step explanation:

1. We know all the angles in a triangle add up to 180 degrees.

<em>180 = x + x + 15 + R</em>

2. Combine like terms

<em>180 = 2x + 15 + R</em>

3. Subtract 15 from both sides

<em>165 = 2x + R</em>

4. Divide both sides by 2

<em>82.5 = x + R</em>

5. Subtract x from both sides

<em>82.5 - x = R</em>

50 is 40% of what number??????
kvv77 [185]
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so

50=40%
divide both sides by 2
25=20%

20 times 5=100 so
multiply both sides by 5
125=100%

Two planes are flying towards each other. In 45 minutes, the two planes will be
ELEN [110]

The distance between the two planes will be 800 miles.

It should be noted that the total speed of the two planes will be the sum of their individual speeds. Also, the planes have 1 hour to meet each other.

From the information given, the distance between the planes is 200 miles after they flew for 45 minutes. Therefore, the remaining distance will be:

= 1 hour - 45 minutes = 15 minutes.

The distance between the planes will then be:

= 200/15 × 60

= 200 × 4

= 800 miles

Therefore, the distance between the two planes will be 800 miles.

X^2 + Y^2 +ax + 2y + 3 = 0<br><br> What number is this equation the equation of a circle?
Sav [38]

Answer:

Eq: (x+a/2)²+(y+1)²=(a²-8)/4

Center: O(-a/2, -1)

Radius: r=0.5×sqrt(a²-8)

Mandatory: a>2×sqrt(2)

Step-by-step explanation:

The circle with center in O(xo,yo) and radius r has the equation:

(x-xo)²+(y-yo)²=r²

We have:

x²+y²+ax+2y+3=0

But: x²+ax=x²+2(a/2)x+a²/4-a²/4= (x+a/2)²-a²/4

And

y²+2y+3=y²+2y+1+2=(y+1)²+2

Replacing, we get:

(x+a/2)²-a²/4+(y+1)²+2=0

(x+a/2)²+(y+1)²=a²/4-2=(a²-8)/4

By visual inspection we note that:

- center of circle: O(-a/2, -1)

- radius: r=sqrt((a²-8)/4)=0.5×sqrt(a²-8). This means a²>8 or a>2×sqrt(2)
