<h2>Answer: </h2>
<u>In a right triangle, Relation of base and hypotenuse is cosine</u>.
cos40° = 10/h
0.76604 = 10 × h
0.76604h = 10
h = 10/0.76604 = 13.05units.
Answer: Tristan can pick them out in 6 different ways
Step-by-step explanation: In the waiting room the four magazines all have an equal chance of being picked first and then others would be picked subsequently. If we are to pick magazine A first of all, then the others would be picked as B, C and D, or C, B and D, or D, B and C, and so on.
However, rather than spend so much time counting the different ways we can apply the mathematical method of permutation. Since choosing the first one means we can’t choose it again but others have to be chosen, and all four magazines each has an equal chance of being chosen first, then the number of all possible permutations is given as 4! (four factorial).
The question requires us to chose three out of the four magazines, so we shall apply 3!.
3! = 3 x 2 x 1
3! = 6
Therefore, there are 6 different ways to pick three out of the four magazines
Answer:
6 units
Step-by-step explanation:
They are on the same y-point and so you just have to count the spaces between them on the x-axis.
