What is the value of x <br><br>x=2.25<br>X= 11.25<br>x= 13<br>x= 22
Gemiola [76]

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

see the attached figure with letters to better understand the problem

m∠B+(6x+1)=180°-----> by supplementary angles

m∠B=179-6x

m∠A=2x+10

m∠C=79

m∠A+m∠B+m∠C=180

Substitute

(2x+10)+(179-6x)+79=180\\ -4x+268=180\\ 4x=268-180\\ 4x=88\\ x=22\ degrees

therefore

the answer is

the value of x is equal to 22\ degrees
