Two angles in a triangle measure (2.3x+25)° and (5.8x+11)°. what is the value of x if the two angles are congruent to one another?

A. x= 34.2
B. x= 10.3
C. x= 6.6
D. x= 4

The answer is D. x= 4

Step-by-step explanation:

The angles are congruent so

2.3x +25 = 5.8x + 11

2.3x - 5.8x = 11 - 25

-3.5x = -14

x = 14/3.5

x = 4.

The answer to your question is the letter D.

Step-by-step explanation:

Data

First angle          2.3x + 25

Second angle    5.8x + 11

Process

1.- This angles are congruents, this menas that they measure the same so to find x, equal both values.

                         2.3x + 25 = 5.8x + 11

2.- Solve for x

                         2.3x - 5.8x = 11 - 25

3.- Simplification

                                -3.5x = -14

                                      x = -14/-3.5

4.- Result

                                     x = 4

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
