Answer:
The marked angle GEF is 25
Step-by-step explanation:
Here, we want to calculate the value of the marked angle
Mathematically, a diagram should do justice to this
Please check the attachment for the diagram
The theorem we want to use is that the sum of opposite interior angles equals the exterior angle
Thus, mathematically;
2x + 1 + x + 19 = 6x + 2
3x + 20 = 6x + 2
6x-3x = 20-2
3x = 18
x = 18/3
x = 6
The angle marked GEF is x + 19
That will be 6 + 19 = 25
Answer:
The probability of winning the bet is 1/336
Step-by-step explanation:
We should understand that there is only one possible arrangement of the winning selection
Now, the horse that comes first can be selected in 8 ways given that all the horses have equal chances
The horse that comes second can be selected in 7 ways given that all the horses have equal chances
The horse that comes third can be selected in 6 ways given that all the horses have equal chances
Now the total number of ways of selection would be;
8 * 7 * 6 = 336
Since there is only one of the selections that is correct, the probability of making the correct choice is thus 1/336
3.2⁴ = 3.2 · 3.2 · 3.2 · 3.2 = 104.8576
D) square the number and add 2
