An example of an angle measurement problem is when trying to
calculate for the height of a particular object given the distance of the
observer from the object and the angle of elevation or depression. For example, you want to find out the height
of a building. All you need to know is the distance of your point of origin to
the building and the angle of elevation.
Answer:
(77, 77)
Step-by-step explanation:
Carry out the indicated multiplication:
3(-0.8, 6.3) → (-2.4, 18.9)
Next, combine like terms:
(79.4, 58.1) + (-2.4, 18.9). In other words, combine the x terms 79.4 and -2.4 separately and then the y terms 58.1 and 18.9 separately:
(79.4, 58.1) + (-2.4, 18.9) → (77, 77)
Answer: 
Step-by-step explanation:
You need to use the SAS area formula. This is:

Given the triangle ABC, you know that:

Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:
