Step-by-step explanation:
since the triangle CDE is an isoceles triangle (the 2 legs DC and DE are equally), the 2 angles at its baseline CE are equal.
combined with the fact that the sum of all angles in a triangle is always 180 degrees we can therefore say :
180 = 32 + 2× base angle
148 = 2× base angle
base angle = 74 degrees.
the angle DEC is one of these base angles and therefore 74 degrees.
and because of the symmetry of angles of crossing lines, this is equal to the angle AEB.
the triangle AEB is also an isoceles triangle. the angle A is one of its base angles at the baseline AB.
so, the same principle as before :
180 = 74 + 2× base angle
106 = 2× base angle
base angle = 53 degrees.
so, angle A is 53 degrees.
When the person is less than 18 years old, out of 265 persons, 20 has job and 245 do not have job.
The probability is defined as 
.
Consider the first column only.
The probability that a randomly selected person surveyed has job is
n=number of hours
inequality = 3n+10=40
Solution = n = 10. So 10 hours.
The probability should be 50/50
Explanation:
Because each time you roll a dice it’s a 50/50 chance to get any number regardless of the number they roll on
Does it have multiple correct answers?
