Angles ABC and DBE are vertical angles where m∠ABC = (7x + 7)° and m∠DBE = (8x − 4)°.
2 answers:
Answer:
x =11
Step-by-step explanation:
2 vertical angles must equal up to 180 degrees to be considered supplementary. The equation given is not supplementary because the angles add up to 168.
Answer:
A) x = 11, B) No, the angles are not supplementary --------------------------------------------------
<h2>Given</h2>
Vertical angles ABC and DBE, m∠ABC = (7x + 7)° and m∠DBE = (8x − 4)°.
<h2>Part A</h2><h3>Find the value of x</h3>
Vertical angles are congruent, hence:
7x + 7 = 8x - 4 8x - 7x = 7 + 4 x = 11 <h2 /><h2>Part B</h2>
<h3>Find the measure of each angle</h3>
Vertical angles are also supplementary if they are right angles . The given angles are not right angles and therefore not supplementary .
