Sine of the angle = opposite side over the hypotenuse
sin(42°) = 6.5/h
rearrange, solve for h
h = 6.5/sin(42°)
h = 9.7 cm
For the other triangle, the angle is unknown. I'd split it into two right triangles; down angle x since it is an isosceles it will be bisected into two equivalent triangles.
The hypotenuse we just found is now split in half. 9.7/2 = 4.9 base of the new smaller right triangle.
The new hypotenuse of the smaller triangle is 7.4 cm
Then you have..
sin(x/2) = 4.9/7.4
sin(x/2) = 0.67
use inverse sine function
arcSin(0.67) = x/2
41 = x/2
82° = x
There are many ways to solve this problem. This is just what I thought of first using trig.
Start at 60
hike down 137 below so new is 60-137=-77m
then go down again 57
-77-57=-134
new altitude is -134m
Answer:
The total number of ways to select 9 women and 4 men for the committee is 50,050.
Step-by-step explanation:
The club has 13 female members and 8 male members.
The committee to be formed must have 9 female members and 4 male members.
The possible number of ways to select 9 female from 13 females is:
The possible number of ways to select 4 male from 8 males is:
Compute the possible total number of ways to select 9 women and 4 men for the committee as follows:
Total number of ways to select 9 women and 4 men = n (F) × n (M)
Thus, the total number of ways to select 9 women and 4 men for the committee is 50,050.
