Chris works in a tall building in downtown Columbia. We are going to view this
skyscraper as a line segment. The building has
an endpoint of point A at the top of the
building, and an endpoint C at the front
door. The building is 43 stories tall. So we
know that the length of AC = 43. Chris
works at point B on the building which is 12
stories above C. Find the length of AB.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
