Answer: IT IS CONGRUENT BY ASA POSTULATE.

Step-by-step explanation:

ACCORDING TO THE GIVEN IMAGE

CONSIDER TRIANGLE 1 AS TRIANGLE ABC AND TRIANGLE 2 AS TRIANGLE PQR

IN TRIANGLE ABC AND PQR

ANGLE B = ANGLE C ( 90 DEGREES )

AC = PR ( GIVEN IN FIGURE )

A TRIANGLE HAS SUM OF INTERIOR ANGLES AS 180 DEGREES

IF ANGLE B AND ANGLE Q ARE 90 DEGREES, ANGLE A + ANGLE C = ANGLE P + ANGLE R

WE HAVE ALREADY PROVED THAT AC = PR

If two triangles have one angle equal to one angle, two sides adjoining the equal angles equal, namely, one side adjoining the equal angles, and one opposite the equal angles, and the remaining angles either both less or both not less than a right angle, then the remaining side equals the remaining side and the remaining angles equal the remaining angles.

SO ANGLE A = ANGLE P

THEREFORE BY ASA CONGRUENCY TRIANGLE ABC IS CONGRUENT TO TRIANGLE PQR

HOPE IT HELPS YOU......

the equation y = 1/5x represents a proportional relationship. explain how you can tell the relationship is proportional from the
Pachacha [2.7K]

Answer:

Yes, y = \frac{1}{5} x represents a proportional relationship and the constant of proportionality is \frac{1}{5}

Step-by-step explanation:

<em>The Proportional is a relationship between two quantity one of them equals the product of the other and a constant, where this constant called the constant of proportionality </em>

  • If x and y are proportion, then y = k x, where k is the constant of proportionality
  • The proportional relationship represented graphically by a line passing through the origin point (0, 0)

Let us solve the question

∵ y = \frac{1}{5} x

→ It the same as the form of the proportional equation above

∵  \frac{1}{5}  is a constant

∴ y is the product of x and constant

∴ y =  \frac{1}{5} x represents a proportional relationship

Substitute x by 0 to find y and show it represented by a line passing through the origin

∵ x = 0

∴ y = \frac{1}{5} (0) = 0

→ That means point (0, 0) lies on the line which represents the equation

∴ The line which represents this relation is passing through the origin

∴ y = \frac{1}{5} x represents a proportional relationship

∵ y = kx, k is the constant of proportionality

∵ y = \frac{1}{5} x

∴ k =  \frac{1}{5}

∴ The constant of proportionality is \frac{1}{5}

Welp lol &lt;3 find the value of x that makes j||k
alukav5142 [94]

Answer: C. 42

Step-by-step explanation:

(3x + 3) is the same angle as 129.

So, you have to equal them to each other.

3x + 3 = 129

Now you solve.

Subtract 3 from each sides.

3x = 126

Divide 3 from each side.

x=42
