You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)

Answer:

Following Theorems and postulates used to prove two triangles are congruent:

1). Side-Side-Side ( SSS ) congruence rule,

When three sides of one triangle are equal to three sides of another triangle , then the two triangles are congruent

2). Side-Angle-Side ( SAS ) congruence rule,

When two sides of one triangle are equal to two sides of another triangle and the an angle between two sides of one triangle equal to angle between two sides of another triangle , then the two triangles are congruent

3). Angle-Side-Angle ( ASA ) Congruence Rule,

When two angles of one triangle are equal to two angles of another triangle and side between two angles of one triangle equal to side between two angles of another triangle, then the two triangles are congruent.

4). Right angle - Hypotenuse - side ( RHS ) Congruence Rule,

If in two right triangles the hypotenuse and one side of on triangle are equal tot he hypotenuse and one side of other triangle, then the triangles are congruent.

Note:

there is also Angle-Angle-Side ( AAS ) Congruence Rule,

When two angles of one triangle are equal to two angles of another triangle and any side of one triangle equal to any side of another triangle, then the two triangles are congruent.

On the blueprint of a house, 40 millimeters represents 6 meters. The length of the living room is 50 millimeters on the blueprin
Novay_Z [31]

Answer:

Convert the meters to millimeters

1m = 1000mm

6m = 6000mm

40mm represents 6000mm

Find the scale factor

6000/40 = 150

This means 40 * 150 = 6000

Yup find what 50mm represents:

50 * 150 = 7500

7500mm

7.5m

Use an algebraic approach to solve the problem.
qaws [65]

Answer:

Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.

Step-by-step explanation:

Use the formula for the mean: sum of elements / number of elements

Let x represent her first exam score.

Her second exam score can be represented by x + 11, since it was 11 points better than her first.

Her third exam score can be represented by (x + 11) + 5, since it was 5 points better than her second.

Plug in all of these expressions into the mean formula. Plug in 87 as the mean, and plug in 3 as the number of elements (since there are 3 scores):

mean = sum of elements / number of elements

87 =  ( (x) + (x + 11) + (x + 11) + 5 ) / 3

Add like terms and solve for x:

87 = (3x + 27) / 3

261 = 3x + 27

234 = 3x

78 = x

So, her first score was a 78.

Find her second score by adding 11 to this:

78 + 11 = 89

Find her third score by adding 5 to the second score:

89 + 5 = 94

Her first exam score was a 78, her second exam score was a 89, and his third exam score was a 94.

Find the are of the trapizoind
Andreyy89

9514 1404 393

Answer:

  7.5 square units

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.

Here, the bases are TR = 1 and PA = 4. The height is 3 units, so the area is ...

  A = (1/2)(1 +4)(3) = 15/2 = 7.5 . . . . square units
