Answer: The answers are given below.
Step-by-step explanation: Given that we are assembling pieces of an iron gate to complete a fence. The finished gate will look like the figure as given in the question.
Part 1: We can clearly see in the picture given that pieces 1 and 2 are placed at an angle of 90° to each other. Therefore, the pieces 1 and 2 are perpendicular to each other.
Part 2: Also, it can be seen that in the centre of the gate, the rectangular sections 5 and 6 are placed at an angle of 0° to each other. Therefore, sections 5 and 6 are parallel to each other.
Thus, 1 and 2 are perpendicular; 5 and 6 are parallel to each other.
Answer:
-3/9x
Step-by-step explanation:
You rearrange for 'y' so divide both sides by it's coefficient which is 9.
Answer:
35 degrees
Step-by-step explanation:
90 -55 = 35
Answer:
x = 12
Step-by-step explanation:
Δ ESR and Δ EGF are similar, then ratios of corresponding sides are equal, so
= 
, substitute values
= 
( cross- multiply )
55(12x - 3) = 6435 ( divide both sides by 55 )
12x - 3 = 117 ( add 3 to both sides )
12x = 120 ( divide both sides by 12 )
x = 10
Answer:
slope = 
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )
m = 
= 
=
