Step-by-step explanation:
Matrix has 5 rows and 3 columns.
So it's order is 5x3.
404 is the answer. if you add them all together
Maybe c or A not completely sure try looking for the one you think it is and try reading it again
Draw a triangle with shortest side on the ground (horiz.). The length of this side is 80 feet. Two angles touch the ground: a right angle, and the 70 degree angle.
Then the height of the building is the 2nd shortest side.
The tangent function is the appropriate one to use here:
opp h
tan 70 deg = -------- = ----------
adj 80 ft
h
Since tan 70 deg = 2.75, 2.75 = -------
80 ft
so h = building height = (80 ft)(2.75) = 219.8 ft
