Answer:
(x - 3)² + (y + 4)² = 90 or [3√10)²
Step-by-step explanation:
We need to calculate the radius of this circle. To do this we calculate the distance from the center (3, -4) to the point (6, 5).
As we move from (3, -4) to (6, 5), x (the run) increases by 3 and y (the run) increases by 9. Thus, the distance between these points, according to the Pythagorean Theorem, is
r = √[3² + 9²], or r = √90, or r = 3√10.
Using the standard equation of the circle, (x - h)² + (y - k)² = r², we obtain
(x - 3)² + (y + 4)² = 90 or [3√10)²
Whats the answer to x+4=-x-4
x+4=(-x)-4
Answer -
Let's solve your equation step-by-step.
x+4=−x−4
Step 1: Add x to both sides.
x+4+x=−x−4+x
2x+4=−4
Step 2: Subtract 4 from both sides.
2x+4−4=−4−4
2x=−8
Step 3: Divide both sides by 2.
2x/2 =
−8/2 =
x=−4
Answer:
x=−4
Answer:
x=29
∠C=93°
Step-by-step explanation:
180°-52°-35°=3(x+2)°
180°-87°=(3x)°+6°
93°=(3x)°+6°
(3x)°=87°
x=
x=29
∠C=3(x+2)°
=3(29+2)°
=3(31)°
=93°
