No they are not similar

Step-by-step explanation:

To make them similar, they would have to have the same angle measurements. The first triangle has 81, and 60 if you add them then subtract the sum by 180 you get the last angle measure, which is 39. 39 is not the same as 40 in the second triangle, proving they do not have the same angles and are not similar

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
