Find the value of x.

Mathematics
1 answer:
ella [17]3 years ago
7 0

Answer:

x = 6

Step-by-step explanation:

(3x + 20)° are vertical angles with (5x + 8)° meaning that they are the same

3x + 20 = 5x + 8

20 - 8 = 5x - 3x

12 = 2x

2x/2 = 12/2

x = 6

How do you use the triangle sum theorem to find the measure of each angle in degrees ?!
TEA [102]

Answer:

The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.

---------------------------------------------------------------------------------

Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°

Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)

Ask in the comments below if you are not sure about something.

I hope that helps you! :D

14) the slope for the first problem is -2/8.
Not proportional

15) The slope is 1/6.
Not proportional

16) The slope is 0.
Not proportional

To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0).

Hope this helps! Merry Christmas!✨❤️

Answer:

Step-by-step explanation:

Let x = third side

Using the Triangle Inequality theorem which states that the sum of two sides of a triangle must be longer than the third side and the difference of the two sides is the lower limit of the third side, the answer to your question is that the third side must be between 3 and 13, or written using inequalities, 3 < third side (or x) < 13 is the range.
