Find the value of x that makes the triangles similar
HELPP !!

X=-2.25

Step-by-step explanation:

8+10+3(x-1)=7.5+x-1+4

18+3x-3=10.5+x

15+3x=10.5+x

3x-x=10.5-15

2x=-4.5

x=-2.25

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 %
