Answer:
21
Step-by-step explanation:
There are two parallel lines given.
Two transversals cut them.
Here m and n are parallel.
Two transversals cut them so that a triangle is formed.
Let us use the property that sum of angles of a triangle = 180
Bottom angle of triangle = 39 (vertically opposite angles)
Top left angle = 4x+3 (vertically opposite angles)
Top right angle = 180-6x (linear pair property)
Now add these 3 and equate to 180
39+4x+3+180-6x = 180
2x = 42
Or x = 21
Answer:
<h2>
y = 3x - 1</h2>
Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = -1/3x + 7 ⇒ m₁=-1/3
-1/3×m₂ = -1 ⇒ m₂ = 3
The y-intercept is b=-1 so the equation in slope-intercept form:
y = 3x - 1
Answer:
(−33)(−34) = 1122
n × ( n + 1 ) = 1122 This gives n 2 + 1 n = 1122 subtracting both sides by 1122 gives n 2 + 1 n − 1122 = 1122 − 1122 or n 2 + 1 n − 1122 = 0 1122 = 33 × 34 ( n − 33 ) × ( n + 34 ) = 0 n = 33 or n = − 34 Negative factors are asked for, so reject n = 33 The factors are − 33 and − 34
