Find the length of side x in simplest radical form with a rational denominator. 30° 60° 7 x

m∠a is 90°

m∠b is 40°

i dont know

step-by-step explanation:

the reason i dont know is because i have not taken this class and for that reason i haven't learned this stuff

hope i could

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2

next time, share the answer choices.   .

well, if you graph the linear equation using intercepts or other methods, and the line is straight, then the equation is linear
