Answer:

1.) x = -2   2.) x = -4   3.) x = -3   4.) x = 2  5.) x=2

Step-by-step explanation:

1. Subtract 5 from both sides.

-4x=13-5

Simplify  13 - 5 to 8

-4x = 8

Divide both sides by -4

x=-8/4

Simplify 8/4 to 2

x= -2

2. Subtract 4 from both sides.

-2x=12-4

Simplify  12-4 to 8.

-2x=8

Divide both sides by −2.

x= -8/2

Simplify 8/2 to 4.

x=-4

3.Regroup terms.

2-x=5

Subtract 2 from both sides.

-x=5-2

Simplify  5-2 to 3.

-x=3

Multiply both sides by −1.

x=-3

4.Subtract 4 from both sides.

x=6-4

Simplify  6-4 to 2.

x=2

5.Subtract 3 from both sides.

11-3=4x

Simplify  11-3 to 8.

8=4x

Divide both sides by 4.

8/4=x

Simplify  8/4 to 2.

2=x

Switch sides.

x=2

Determine if the two triangles are congruent. If they are, state how you know.
Elza [17]
Angle-side-angle is a rule used to prove whether a given set of triangles are congruent. The ASA rule states that: If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent

What is associative property?
Alenkasestr [34]

Associative Property states that grouping symbols does not affect the outcome. This property works for Addition and Multiplication:  

2 + (3 + 4) = (2 + 3) + 4

6 • (5 • 4) = (6 • 5) • 4

In ΔABC, m∠B = m∠C. The angle bisector of ∠B meets AC at point H and the angle bisector of ∠C meets AB at point K. Prove that BH
solniwko [45]

Answer:

See explanation

Step-by-step explanation:

In ΔABC, m∠B = m∠C.

BH is angle B bisector, then by definition of angle bisector

∠CBH ≅ ∠HBK

m∠CBH = m∠HBK = 1/2m∠B

CK is angle C bisector, then by definition of angle bisector

∠BCK ≅ ∠KCH

m∠BCK = m∠KCH = 1/2m∠C

Since m∠B = m∠C, then

m∠CBH = m∠HBK = 1/2m∠B = 1/2m∠C = m∠BCK = m∠KCH   (*)

Consider triangles CBH and BCK. In these triangles,

  • ∠CBH ≅ ∠BCK (from equality (*));
  • ∠HCB ≅ ∠KBC, because m∠B = m∠C;
  • BC ≅CB by reflexive property.

So, triangles CBH and BCK are congruent by ASA postulate.

Congruent triangles have congruent corresponding sides, hence

BH ≅ CK.

Helpppp.............m..​
enot [183]

Answer: 135*

Step-by-step explanation:

35* is what the bottom left side of the triangle angle equals because of congruency.

All triangles = 180*

180 - 100 - 35 = 45*

top angle of triangle = 45 *

said angle (45) +  x angle = 180

x = 135*
