∠1 and \angle3∠3 are vertical angles. If \text{m}\angle1=\left(17x+1\right)\ degreem∠1=(17x+1)° and \text{m}\angle3=\left(20x-14\right) \degreem∠3=(20x−14)°, find the value of x and \text{m}\angle3m∠3.

its 8

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the correct answer is $7.38
