Answer: your answer is going to be 6.
Step-by-step explanation:
Hey there!
<u>Solve </u><u>for </u><u>x </u><u>:</u>
x = 14 ✅
x + 14 = 28
<em>></em><em>></em><em> </em><em>Substrat </em><em>1</em><em>4</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
x + 14 - 14 = 28 - 14
x = 14
<em>▪️</em><em>Let's </em><em>verify</em><em>:</em>
x + 14 = 28 ⇒ 14 + 14 = 28 ✅
Therefore, your answer is x = 14

Answer:
x = -8
Step-by-step explanation:
Let's put this into numbers: x =-6
The first thing you want to do is to multiply both sides by 4:
3x=-24
Next you need to divide by 3:
x=-8
The answer is -8
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°
