If a^2+b^2=c^2 then it's a right angle
If a^2+b^2>c^2 then it's acute
If a^2+b^2< c^2 then it's obtuse. 3.1^2+3^2. 5^2
1+9. < 25
#3 is obtuse
4. 28^2+45^2. 53^2
2809. 2809
#4 is a right triangle
5. 9^2+11^2. 13^2
81+ 121 =202.> 169
#5 is acute
The business bureau surveys all the convention visitors who stay at the hotel nearest the convention hall.
Diagonals that bisect each other are perpendicular and form a right angle.
AEB is a right triangle.
We can apply the Pythagorean theorem:
c^2 = a^2+b^2
Where c is the hypotenuse (longest side) and a and b the other 2 legs.
Replacing:
AB^2 = AE^2+BE^2
AB^2 = 5^2+12^2
AB^2 = 25+144
AB^2 = 169
AB=√169 = 13
Lenght of AB= 13
The complete question in the attached figure
we know that
[arcs rc +arc cs arc sm]---------------> they take up half a circle-------->180°
<span> they are all congruent
so
divide 180 by 3 ----------------> 180/3=60</span>°
Find the length of arc rc=60°<span>
if 360</span>°----------------> (2*pi*7) length of circumference
60° -------------------> X
<span>X=60*2*pi*7/360------------> 7.327 units
the answer is
</span>
the length of arc rc= <span>
7.33 units</span>
