Answer:
x + 100+ 3x = 180
4x + 100 = 180
4x = 180-100
<u>4</u><u>x</u><u> </u> = <u>8</u><u>0</u>
4. 4
x= 20°
Answer:
Top Right
Step-by-step explanation:
231/pi(3)^2 =8.17
Round down to 8
We need to solve the equation to find x
We will simplify the left side by multiply each bracket by the number before it
-3(x - 6) = -3(x) + -3(-6) = -3x + 18
4(x + 1) = 4(x) + 4(1) = 4x + 4
Now put them on the left side
Add the like terms on the left side
Now we will collect x on the right side and the numbers on the left side
Subtract x from both sides
Add 14 to both sides
Divide both sides by 6 to find x
The value of x is 6
a. 2. a->b is transversal
b. Statement: a and b are supplementary
Reason: angle a is 145 deg and angle b is 35 deg, the two angles add up to 180 degrees.
c. If you measure one angle and then subtract it from 180 you get the other angle.
3. The exterior angles
a. a and 2 are both 145 deg, 1 and b are both 35 deg
b. the fact that you can subtract one from 180 to get the other.
c. 145 degrees
4. Reflection
a. train tracks, roads.
b. The fact that the slope exists is a fairly major issue, using imaginary concepts allows for more freedom of geometric expression, an example of this is basically all of subspace and hyperspacial theory. Since it is purely theoretical and thus imaginary greater freedom is offered to generate theories and structures.
It is solution c. You substitute ABC for DEF.
