Answer:
x = 25°
Step-by-step explanation:
Applying,
Sum of the angle in the triangle = 180°
From the diagram,
First angle of the triangle = 55° (vertically opposite angles are equal)
Second angle of the traingle = 180-80 = 100° (sum of the angle in a straight line)
Third angle of the triangle = x
Therefore,
x+55+100 = 180
x+155 = 180
x = 180-155
x = 25°
Answer: a. 0.6759 b. 0.3752 c. 0.1480
Step-by-step explanation:
Given : The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard deviation of 2.2 minutes
i.e. 
minutes
minutes
Let x be the long-distance call length.
a. The probability that a call lasts between 5 and 10 minutes will be :-
b. The probability that a call lasts more than 7 minutes. :

Answer:
M
Step-by-step explanation:
The angle bisector is M
By the definition of a rectangle, JML and KLM are right angles.
<h3>How to explain the information?</h3>
From the information given, JKLM is a rectangle based on the definition as the opposite sides are equal.
Also, JML and KLM will be 90° since they're right angles. The opposite sides of a rectangle are congruent and equal.
