∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ ,
blsea [12.9K]

Answer:

108 degrees

Step-by-step explanation:

Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:

Combine like terms: 14x - 16 = 180

Add 16 to both sides: 14x = 196

Divide both sides by 14: x = 14

Now that you know x, you can plug it into the expression for angle A (7x+10):

A = 7(14) + 10 = 98+10 = 108

How many triangles can be formed with segments measuring 34 cm, 13 cm, and 38 cm? Select from the drop-down menu to correctly co
Lilit [14]

The triangle inequality theorem is not followed,  no triangle can be formed.

Triangles

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 34 cm, 13 cm, and 38 cm.

34cm + 13 cm = 47 cm > 38cm (theorem followed)

34 cm + 38 cm = 72 cm > 13 cm (theorem followed)

13 cm + 38 cm = 51 cm < 34 cm (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.
