Triangle ABC has a horizontal sido AC, and AB in perpendicular to BC. A vertical line is drawn from a point labeled Don AC to the point 8. Which of the following statements are true? Select the two correct answers.

Option (3)

Step-by-step explanation:

Given:

Horizontal side of a triangle ABC is side AC.

AB and BC are the perpendicular lines.

BD is perpendicular to side AC.

Solution:

Option (1).

Slopes of AB and BC are reciprocal.

False.

Option (2)

Angle DAB and BCD are equal.

False.

Option (3).

Since, sides AB and BC are perpendicular lines,

Slopes of AB and BC will be negative reciprocals.

True.

Option (4).

Triangles ABD and BCD are similar.

False.

Therefore, Option (3) will be the answer.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

the correct answer is $7.38
