Answer:
y = 29/4
Step-by-step explanation:
It is given that,
3/(y - 5) = 15/(y + 4)
<u>To find the value of y</u>
we have,
3/(y - 5) = 15/(y + 4)
3(y + 4) = 15(y - 5)
(y + 4) = 5(y - 5) [dividing both sides by 3]
y + 4 = 5y - 25
5y - 25 = y + 4
5y - y = 4 + 25
4y = 29
y = 29/4
Therefore the value of y = 29/4
Answer:
your answer would be 4.2 x 10-4
Step-by-step explanation:
Answer:
m∠ABC = m∠BED; Corresponding Angles Theorem
Step-by-step explanation:
<u>Given:</u> line BC is parallel to line ED m∠ABC = 70° m∠CED = 30°
<u>Prove:</u> m∠BEC = 40°
Statement Justification
1. line BC is parallel to line ED - Given
2. m∠ABC = 70° - Given
3. m∠CED = 30° - Given
4. m∠BEC + m∠CED = m∠BED - Angle Addition Postulate
5. m∠ABC = m∠BED - Corresponding Angles Theorem
6. m∠BEC + 30° = 70° - Substitution Property of Equality
7. m∠BEC = 40° Subtraction Property of Equality
