Which is the equivalent of 145.12° written in DMS form?

145° 7' 12"

Step-by-step explanation:

145.12° written in DMS form

145°

0.12 *60 (1 degree = 60 minutes)=7.2 minutes

0.2*60 ( 1 minute=60 sec)=0.2*60=12"

109 is the nearest whole number/final answer! : )

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
