Question

the measures of two angles are 2 X + 1 and 2 x-1 and they are supplementary angles find the value of x​

Answer 1

Step-by-step explanation:

if two angle are supplementry then some of these angle will be 180

: 2x+1+(2x-1) = 180

2x+1+2x-1=180

4x =180

x=180/4

x=45

Answer 2

Two angles are called supplementary if their sum of angles is 180°.

Two angles are called complementary if their sum of angles is 90°.

2x+1+2x-1=180

4x=180

x=180/4

x=45
