2/3h=r
2/3h=6
h=9
 
You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
 
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)

(9) As this is just 1 triangle you then need to multiply it by 2

bh = sqrt of 3 over 3 * 9</span><span>

SpyIntel [72]

Answer:

Total number of girls in Alden Middle school= 25 girls

Percent of girls play for travel team= 40%

We have to find the numbers of girls who play for middle school team

Numbers of girls who play for middle school team= 25 ×\frac{40}{100}

Numbers of girls who play for middle school team=25 ×\frac{40}{100}

Need Help With Math. One Question

Answer: 2 < x < 16

The triangle inequality theorem says that if we have a triangle with sides a,b,c then

b-a < c < b+a

with b being longer than 'a'

In this case, a = 7 and b = 9 and c = x

so we have

b-a < c < b+a

9-7 < c < 9+7 .... replace a with 7, replace b with 9

2 < c < 16

2 < x < 16 .... replace c with x

So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
