A is the correct answer. Hope this helps. I need brainliest so if you can I really appreciate it!
1/5(100x - 105y + 70) = 20x -21y + 14
Answer:
(a) The total area of compound figure is
.
(b) The total perimeter of compound figure is 68.84 ft.
Step-by-step explanation:
Perimeter: The total distance covered by the figure.
Area: It is defined as the space occupied by the figure.
Given:
Length of rectangular figure = 19 ft
Breadth of rectangular figure = 12 ft
Radius of circle, r = 
Part (a):
Now calculating the total area of the compound figure.

Now putting all the given values in this formula, we get:

Part (b):
Now calculating the total perimeter of the compound figure.

Now putting all the given values in this formula, we get:

Answer:
Step-by-step explanation:
Part A
Since, the given angles are formed at a point are on a straight line, sum of these angles will be 180°.
Part B
(3x - 5)° + (4x + 2)° + (2x + 3)° = 180°
9x = 180
x = 20
Part C
m∠ADB = (3x - 5)°
= (3×20 - 5)°
= 55°
m∠DBK = (4x + 2)°
= (4×20 + 2)°
= 82°
m∠KBC = (2x + 3)°
= (2×20 + 3)°
= 43°
Answer:
Yes
