A quadrilateral has angles that measure 101, 133º, and 76º.
What is the measure of the fourth angle?

50°

Step-by-step explanation:

101 + 133 + 76 +x = 360

310 + x = 360

x = 50

d. vertex

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 %
