Mathematics
1 answer:
bekas [8.4K]3 years ago
7 0

Answer:

225

Explanation:

∠ADC is a right angle [definition of altitude]. ∠ADC = 4x - 10, and since all right angles are 90° >> 4x - 10=90 >> 4x -10+10= 90+10 >> 4x=100 >> 4x/4=100/4 >> x=25.

BD+DC=BC [Between-ness of points] >> 4x + 5x -3=BC >> we know that x=25, so by substitute property >> 4*25+5*25 -3=BC >> 100+125 -3=BC >> 222=BC

Rosa works in an office building with many floors.From her office she goes down 5 floors for a meeting .Then she goes up 8 floor
n200080 [17]

Answer:

11th floor

Step-by-step explanation:

So to figure out what floor Rosa's office is in, we need to declare some variables.

x = Rosa's office

down 5 floors = -5

up 8 floors = 8

down 13 floors = - 13

One major clue to find Rosa's office is that she went down 13 floors to get to the 1st floor. So let's declare that Rosa is on the first floor.

x - 5 + 8 - 13 = 1

x - 10 = 1

x = 1 + 10

x = 11

So Rosa's office is at the 11th floor of the building.
