Step-by-step explanation:
1. 18(5)=90 18(6)=108
90*108= 9720
Her size of the original work was 9720 inches.
2. 1/2+1/2= 1 1/2=4 ft
The pole is 8 feet tall
3. 3 feet
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for third angle
third angle = 180° - (39 + 56)° = 180° - 95° = 85° → A

Answer:
![\fbox {Trapezoid ABCD and Trapezoid EFGH are congruent.}](https://tex.z-dn.net/?f=%5Cfbox%20%7BTrapezoid%20ABCD%20and%20Trapezoid%20EFGH%20are%20congruent.%7D)
Step-by-step explanation:
<u>Finding corresponding side lengths</u> :
<u>Trapezium ABCD</u>
- AB = √(-2)² + (-1)² = √5
- BC = √(-1)² + (2)² = √5
- CD = √(2)² + (2)² = 2√2
- DA = √(-1)² + (5)² = √26
<u>Trapezium EFGH</u>
- EF = √(2)² + (1)² = √5
- FG = √(1)² + (2)² = √5
- GH = √(-2)² + (2)² = 2√2
- HE = √(1)² + (5)² = √26
As the corresponding side lengths are equal, we can conclude that the trapezoids are congruent.
