then, 
, where we need to find an expression for using the law of cosines.
Replacing all expression, the perimeter is
Using a calculator, the perimeter is 20 units centimeters.
Answer:
about 52 (51.6 to be exact) sixth graders walk to school!
Step-by-step explanation:
1. take 24 and times it by 215
2. divide the above by 100
3. this will give you 51.6
4. round for an approximate value
Answer:
Step-by-step explanation:
The measure of arc which the right triange cuts from the circle is 
this means the central angle has the same measure.
Angle with measure 
is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence
Angles with measures and 
are complementary angles (add up to 90°), so
Answer:
height=100feet
Step-by-step explanation:
perimeter of a rectangle=p=500 feet
p=2a+2b equation 1
a=height
b=base
we have: b/a=3/2
so a=(2*b)/3
in equation 1 we have:
500=2*((2*b)/3)+2*b
so we have
500=(4*b)/3 + 2*b
500=(4b+6b)/3
500=(10b)/3
500*3=10b
b=(500*3)/10
b=150 feet =base
so
a=(2*150)/3=100 feet = height
