Answer: x= 5
Step-by-step explanation: Distribute the -7 into the parentheses, we get 14x+63=133. You then minus 63 on the left side of the equation and on the right side of the equation. You will get 14x=70. You then solve x by dividing 70 by 14 you will get x=5.
Substitute (-1)3-(-1)+(-1)0
multiply (-3)+1+0
simplify. -2
Final Answer: -2
With intersecting lines, the angles opposite the intersection (across the "X") are called vertical angles, and they are identical. Therefore JNK = MNL and KNL = JNM.
So set KNL = JNM:
3(x+14) = 5x+2
3x+42 = 5x+2
3x+42 -42 = 5x+2 -42
3x = 5x -40
3x -5x = 5x-5x -40
-2x = -40
-2x/-2 = -40/-2
x = 20
Now plug that into x for KNL:
KNL = 3(x+14) = 3(20+14) = 3(34) = 102°
The area of a shape is the amount of space on it:
The shaded area is 314 square centimeters
<h3>How to determine the shaded area</h3>
Start by calculating the area of sectors OFG and OAD using:
So, we have:
Also, we have:
Next, calculate the area of the sectors BOE and COH
Note that the radius of these sectors is 6 cm.
So, we have:
The shaded area is then calculated as:
This gives
The equation becomes
Hence, the shaded area is 314 square centimeters
