Triangle STU is congruent to triangle UTX is the missing step. AAS (angle-angle-side) is a method of proving 2 triangles congruent, and using the already proved information, you can find the triangles that are congruent by AAS.

Answer:

5. Statement: \triangle TXU\cong \triangle TSV

Step-by-step explanation:

Given, triangle STU is an equilateral triangle.

\angle TXU \cong \angle TVS

To prove that UX \cong SV

Proof:

1. Statement: \angle TXU \cong \angle TVS

Reason: Given in question .

2. Statement: \angle STV \cong \angle UTX

Reason: By using reflection proeperty of rotation.

3. Statement: \triangle STU is an equilateral triangle.

Reason: \angle STU= \angle TSU=\angle SUT given.

4. Statement: ST \cong UT

Reason: Sides of equilateral triangle STU.

5. \tringle TXU \cong \triangle TSV

Reason: AAS congruence property of triangle.

6. Statement: UX\cong SV

Reason: CPCT ( corresponding parts of congruence triangles).

The largest angle of a triangle is 60° larger than the smallest angle. the middle angle is triple the measure of the smallest an
Alex787 [66]
Total degree in triangle is 180.
so, 180= x + 3x + (x+60)
180 = 5x +60
5x = 180-60
5x = 120
x = 24
Largest angle is 84
Middle angle is 72
Smallest angle is 24

The perimeter of a triangle is 16x−6. If two sides measure 3x+2 and 4x−9, then how long is the third side?
Studentka2010 [4]

Perimeter of a triangle is the sum of measures of its all three sides, let the other be y,

we know,

\hookrightarrow \: y + 3x + 2 + 4x - 9 = 16x - 6

\hookrightarrow \: y + 7x - 7 = 16x - 6

\hookrightarrow \: y = 16x - 6 - 7x + 7

\hookrightarrow \: y = 6x + 1

hence, measure of the third side is 6x + 1
