Step-by-step explanation:
Let us take sin(60 degree + theta) =x
Substituting x in equation
=> x-x
=> 0
Step-by-step explanation:
50-50+15d =125-50
15d = 75
15d/15=75/15
d=5
Answer:
x=65
Step-by-step explanation:
x-5=60
Add 5 to both sides
x=65
Answer:
see explanation
Step-by-step explanation:
Let c represent the number of children, then
number of men = 4c and number of women = 2c
Sum the numbers of each and equate to 266
4c + 2c + c = 266, that is
7c = 266 ( divide both sides by 7 )
c = 38
Thus
4 × 38 = 152 and 2 × 38 = 76
The group consists of 38 children, 152 men and 76 women
