the triangles below are congruent and their corresponding parts are marked. name all the corresponding congruent angles and side
GuDViN [60]

Answer:

See explanation

Step-by-step explanation:

The triangles below are congruent and their corresponding parts are marked.

a) Angles marked with one arc are congruent, so \angle B\cong \angle Z.

Angles marked with two arcs are congruent, so \angle A\cong \angle Y.

Angles marked with three arcs are congruent, so \angle C\cong \angle X.

b) Sides marked with one segment are congruent, so \overline {AC}\cong \overline {YX}.

Sides marked with two segments are congruent, so \overline {BC}\cong \overline {ZX}.

Sides marked with three segments are congruent, so \overline {AB}\cong \overline {YZ}.

c) Name teo congruent triangle following the congruence of angles:

\triangle BCA\cong \triangle ZXY

How can you tell when an equation in one variable has infinitely many solutions or no solution?
Masteriza [31]

Answer:

A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.

Maria solved the equation. 4 (3 x minus 8) minus 4 = 24. 12 x minus 32 minus 4 = 24. 12 x minus 36 = 24. 12 x = 60. x = 5. What
Mrac [35]

Answer:

1. Distributive property.

2. Combining like terms.

3. Addition property of equality.

4. Division property of equality.

Step-by-step explanation:

- The Distributive property states that:

a(b+c)=ab+ac\\\\a(b-c)=ab-ab

- The Addition property of equality states that:

If\ a=b\ then\ a+c=b+c

- The Subtraction property of equality states that:

If\ a=b\ then\ a-c=b-c

- The Multiplication property of equality states that:

If\ a=b\ then\ a*c=b*c

- The Division property of equality states that:

If\ a=b\ then\ \frac{a}{c}=\frac{b}{c}

Given the following equation:

4(3x-8)-4=24

We can identify that the methods Maria used to solve it and the order, are:

1. Distributive property:

(4)(3x)-(4)(8)-4=24\\\\12x-32-4=24

2. Combining (or adding) like terms:

12x-36=24

3. Addition property of equality, because she added 36 to both sides of the equation:

12x-36+36=24+36\\\\12x=60

4. Division property of equality, because she divided both sides of the equation by 12:

\frac{12x}{12}=\frac{60}{12}\\\\x=5
