Answer:
The smallest possible side length is around 21.3.
Step-by-step explanation:
Equilateral triangles have 3 sides of equal lengths.
65 ÷ 3 =
or 21.333
Answer:
Step-by-step explanation:
the width of the first frame is 12cm because 120/10 = 12
the length of the second frame is 24cm because 288/12 = 24
Answer:
10a + 7
Step-by-step explanation:
This problem is asking you to plug in 2a + 3 for x.
g(x) = 5x - 8
g(2a + 3) = 5(2a + 3) - 8 = 10a + 15 - 8 = 10a + 7
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
