Find angle a2 which is 40 degrees because it is parallel to angle c.
Find the total of d1 and d2.
total of d1 and d2: 180 - 40 - 40 = 100 degrees
Find d1 and d2 separately.
100 divided by 2 = 50 degrees
Use d1 to find b1 to find total of a1 and a2.
b1 is parallel to d1 so b1 = 50 degrees
a1 and a2 = 180 - 50 - 50 = 80 degrees
a1 = 80 divided by 2 = 40
Since a1 and c1 are parallel due to alternate angles, c1 is 40 degrees
Find b2 now which requires you to do total - minus all angles in the triangle with angle b2.
180 - 40 - 50 - 40 = 50 degrees (angle b2)
AOB has b1 and a1.
40 + 50 = 90 degrees (a1 + b1 = AOB)
The answer is 90 degrees
Answer:
Step-by-step explanation:
The last one.
A would be a quadratic if the leading coefficient was anything but 0. 0 eleminates the x^2. Not A
B has no x^2 term to begin with. B is not the answer.
C is in exponential form. C is not the answer
D has an x^2 term. There is nothing using x that is higher. D is the answer.
Answer:
B. infinite solutions along a line
Step-by-step explanation:
The matrix is equivalent to the equations ...
x = 2
y = 9
0z = 0 . . . . . . true for any z
This tells you the solutions are ...
(x, y, z) = (2, 9, z)
This defines a line parallel to the z-axis.
1. To solve this problem you must apply the formula for calculate the area of a regular hexagon given the apothem, which is shown below:
A=(Perimeter x Apothem)/2
2. You have the apothem, so you can calculate the perimeter. First, you have to know the lenghts of the sides:
Tan(30°)=x/√3
x=1
Side=2x
Side=2
Perimeter=2x6
Perimeter=12
3. Then, you have that the area of the base is:
A=(Perimeter x Apothem)/2
A=12x√3/2
A=6√3
A=10.39
B=10.39 cm²
The answer is: B=10.39 cm²
Midpoint coordinates are ( - 2 + 2) / 2 , (-1+3) / 2
