Can you post a picture of it, I can’t see the triangles.
Pretty sure the answer is 40. If memory serves correctly you set them equal to each other
The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

How to write algebraic expression? </h3>
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Harry is one third as old as his father and his father is x+12 years old.To find the age of Harry, we need to convert the given statement into the algebraic expression.
Suppose the age of the Harry is <em>a</em> years and the age of his father is<em> b</em> years. Now Harry is one third as old as his father, thus

Let the above equation is equation one.
As the father of Harry is x+12 years old. Thus put the value of age of his father in the equation one as,

The age of the Harry in the terms of variable <em>x, </em>as the age of his father is (x+4) is represent with following equation.

Answer:
if it is a regular quadrilateral and each angle is equal then its 90 degrees
Step-by-step explanation:
When the exercise asks to describe the likelihood of the event using the probabilities means that taking into account that the probabilities are numbers between 0 and 1, see if the events are likely or not to happen.
For a soft drink, which has a 0.80 probability is a likely event that could happen because it is greater to the middle (0.5) but is not so close to 1.
For a daily special, which has a 0.25 probability is more and unlikely event that could still happen but its not so common to.
For dessert, which has a probability of 0.5 probability is neither a likely nor unlike event because the probability is really close to the middle.
For appetizer, which has a probability of 0.06 probability is more an unlikely/impossible event because the probability is so small and close to 0 that it is not common to happen at all.
