Find the value of "x" in the following

(a) 60° (b) 125°

Step-by-step explanation:-

Given are three 's, so,

(As all sides of triangle add upto 180°)

Hence, value of x is 60°

Given two interior angles(55°,70°) & one exterior angle(°)

Hence, value of x is 125°

whatvare the choices

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
