Johan found that on a ruler, 2 feet is equal to 610 millimeters. The diagonal of his television measures 3.5 feet. Which proportion could Johan use to find x, the length of the diagonal of the television screen in millimeters?

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,

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

83-45=38

38 was the other number

hope your goes well, here's a turkey
