Answer:
8 x 10/11 equals 69. If you mean something else, let me know.
Step-by-step explanation:
If you need any help, ask Brainly. Have a nice day!
The two angles are corresponding angles, which means they are equal to each other. Make them equal to each other in an equation.
11x - 2 = 130
Add 2 to both sides.
11x = 132
Divide both sides by 11.
x = 12
The answer is C. when you have questions like these, its best to plug in an easy number and test it out.
Say the original radius was 2. That means the area of that sprinkler was 12.56 (if you use the formula Pi(radius)squared.
a number 3 times bigger then 2, is 6. (2 times 3 = 6) There fore, following the same formula as before, you plug that number in and get 113.04 as the area of the new sprinkler.
113.04 divided by 12.56 is 9
X=-8.5
u would solve by isolating x
