kaheart [24]

Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135

Write the equation of a circle with a center at (-2, 3) and a radius of 4.

Ivan

Answer:

The equation of a circle:

$(x+2)^2+(y-3)^2 = 16$

Step-by-step explanation:

The equation of a circle:

$(x-h)^2+(y-k)^2 = r^2$

(where the center is known as $(h,k)$ and the radius, known as $r$ ).

-Since you already have the center and the radius, use them for the equation of a circle:

Center: $(-2,3)$

Radius: $4$

$(x+2)^2+(y-3)^2 = 4^2$

After you have the equation of a circle, simplify the radius by the exponent $2$ :

$(x+2)^2+(y-3)^2 = 16$

So, you have found the equation of a circle.

Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one a

BartSMP [9]

Answer: The required conclusion is

"if in triangle ABC, AB ≅ AC, then ∠B and ∠C must be congruent".

Step-by-step explanation: Given that in triangle ABC, AB ≅ AC, implies that AB = AC must be true. We are given to assume ∠B and ∠C are not congruent. Then the measure of one angle is greater than the other.

If m∠B > m∠C, then AC > AB because of the triangle parts relationship theorem.

For the same reason, if m∠B < m∠C, then AC < AB.

This is a contradiction to the given information.

We are to state the conclusion.

Since in the beginning, it is given that AB ≅ AC and we have assumed that ∠B and ∠C are not congruent, so

our assumption must be wrong.

That is, ∠B and ∠C must be congruent.

Thus, the required conclusion is

if in triangle ABC, AB ≅ AC, then ∠B and ∠C must be congruent.
