Answer:
No. of gonjas = 52
No. of more nzemas than fantes = 78
Step-by-step explanation:
Total no. of people = 520
No. of fantes = × 520
No. of fantes = 156
No. of ewes = × 520 = 130
No. of nzemas = × 520 = 78
No. of gas = × 520 = 104
No. of gonjas = 520 - (156 + 130 + 78 + 104) = 52
No. of fantes = 156
No. of nzemas = 78
No. of more nzemas than fantes = 156 - 78 = 78
Pie chart of the following problem is shown below.
Answer:
Step-by-step explanation:
By the Pythagorean theorem, triangle BCD has
and triangle ABD has
.
Substituting the first equation into the second equation for gives the equation
Now triangle ABC has
Expanding out the left side, .
Now substitute the equation from before, , into the new equation.
We work to isolate by adding
to both sides of equation and subtracting
from both sides.
Divide both sides by 2 and you get
Assume that x is positive and square root both sides to get the final result of
