Answer:
x = 11
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
The least common multiple between 3 and 4 is 12, so we can use this fact to rewrite both 1/3 and 1/4 in 12ths:

We're left with an answer of
7/12, which can't be reduced.
Answer:
YOU not smartYOU DONT KNOW THIS HA HA NOT HELPING YOU BOT.

The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
Answer:
option D
Lines a and b are parallel and lines c and d are parallel.
Step-by-step explanation:
Given in the question four lines a , b, c, d.
<h3>
Prove one</h3>
If two parallel lines (a,b) are cut by a transversal(d), then corresponding angles m<7 and m<15 are congruent.
They are know as corresponding angles.
Hence lines a and b are parallel.
<h3>Prove two</h3>
If two parallel lines (c,d) are cut by a transversal(d), then corresponding angles m<13 and m<15 are congruent.
They are know as corresponding angles
Hence lines c and d are parallel
