Answer:
A: 360
Step-by-step explanation:
Split the trapezoid into 2 shapes
Then find the area of the rectangle on the left:
18 × 15 = 270 square yards
Now for the triangle, first find the base by subtracting the 2 parallel lines:
25 - 15 = 10 yards
0.5(10 × 18) = 90 square yards
Add both areas to find total area:
270 + 90 = 360 square yards
All this can be seen in the figure below:
An angle bisector is basically a bisector that divides an angle into two congruent parts. So, since one part of the angle is 61°, then the other part of the angle is also 61° by the definition of an angle bisector. The answer is C) Definition of Bisect. Hope this helps and have a great day!

Quesiton 7:
To find perimeter we add all the sides together.
x+2x+2x+5=145
Combine all the x's.
5x+5=145
To isolate the constants, subtract 5 from both sides.
5x=140
Now divide both sides by 5 to isolate the x.
x=28
The questions asks for the length of AC, so to find that we need to insert our new x.
AC= 2(28)+5
56+5=61
Answer:
10/3
Step-by-step explanation:
Answer:
x=-47
Step-by-step explanation:
3(5x+4)=7(2x-5)
15x+12=14x-35
x+12=-35
x=-47
