Question

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

Answer 1

The answer is D. x= 4

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.

Answer 2

The answer to your question is the letter D.

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
