Answer:
24 cm²
Step-by-step explanation:
The area of the shaded region is the area of the outer triangle subtract the area of the rectangle.
Area of triangle = 0.5 × (4 + 4) × (6 + 2) = 0.5 × 8 × 8 = 4 × 8 = 32 cm²
Area of rectangle = 4 × 2 = 8 cm², hence
Shaded area = 32 - 8 = 24 cm²
7.5 gallons. (5x60)/40 5x60 being the equation to find the total miles driven
Answer:
a=101
b=67
c=84
d=80
Step-by-step explanation:
The measure of an intercepted arc will always be twice the measure of the inscribed angle
to find A:
2(100)=a+99
200=a+99
a=101 degrees
d=80 degrees because 100*2=200, 360-200=160, and 160/2=80
You can find c by subtracting 100, 96, and 80 from 360 and you get c=84 degrees
Find the measure of b by using what you found as measure of c and a
2(84)=101+b
168=101+b
b=67
Answer:

Step-by-step explanation:
Subtract 7x from 8x.
Move all terms not containing x to the right side of the equation.
Add 9 and 2.
