Question

The angle measures of a triangle are shown in the diagram.

50
(2x)
(3x - 100
What is the value of x?
O A. 25
B. 20
10
OD. 28

Answer 1

The value of the variable x is 28. Option D

First, we should know that the sum total of the angles in any triangle is 180 degrees.

Since we have that the angles are represented as;

50, (2x), (3x - 10)

Then, we have to equate the angles to 180 degrees, we have the representation as;

50 + 2x + 3x - 10= 180

collect the like terms, we have;

5x = 180 - 40

5x = 140

Divide both sides by the coefficient of x, we get;

x = 28

The complete question:

The angle measures of a triangle are given as;

50 degrees

(2x) degrees

(3x - 10) degrees
