Which one of the following statements is true of perpendicular lines? a. they intersect to form an obtuse angle. b. they intersect at one point. c. they never intersect. d. they intersect to form an acute angle.

B. They intersect at one point.

Step-by-step explanation:

Perpendicular lines intersect at one point at 90 degrees.

Therefore, we ignore options A) , C) and D)

Perpendicular means 90 degrees

Therefore, answer is B. They intersect at one point.

Hope this will helpful.

Thank you.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
