Point D is the centroid of triangle abc. AG is perpendicular to CB and GB = 8, AE = 5.75, AD = 4 and AC = AB. Find AB Numbers on photo - 5.75 and 4, 8.

answer: 1, 3 and 5 are correct

step-by-step explanation:

13.46

step-by-step explanation:

16.80 x .20 = 13.46

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
