5: 5, 10, 15, 20, 25, 30, 35, 40
10: 10, 20, 30, 40
least common multiple is 10
Answer:
X=4
Step-by-step explanation:
Move the variable to the left side
13-4x+x=1
Subtract 13 on both sides
13-4x+x=1
-13 -13
Collect the like terms
-3x= -12
Divide both side4s by -3
-3x/-3= -12/-3
Answer:

Answer:
The sum of angles 3 , 4 and 5 is <u>180°</u>
Alternate interior angles are <u>equal</u>
The sum of the measures of the interior angles equal to <u>180°</u>
Step-by-step explanation:
∵ ∠4 , ∠3 and ∠5 formed a straight angle
∵ The measure of the straight angle = 180°
∴ m∠4 + m∠3 + m∠5 = 180° ⇒ (1)
<em>From the parallelism</em>
m∠4 = m∠1 ⇒ alternate interior angles
m∠5 = m∠2 ⇒ alternate interior angles
<em>By substituting in (1)</em>
∴ m∠1 + m∠3 + m∠2 = 180°
∴ The sum of the measure of the interior angles in a triangle = 180°
