I'll solve 21, and you then should be able to solve the rest on your own!
Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
Simplify them until they can be simplified no more, then compare both sides.
Volume of the cube is 1000 cm³
Step-by-step explanation:
- Step 1: Find the volume of the cube.
Side of the cube = 10 cm
⇒ Volume of the cube =(side)³ = 10³ = 1000 cm³
<span>the x is supposed to represent the amount of miles driven in that car and the numbers in the paranthesis are supposed to be the price of the car or rental cost</span>
